Your website is often the first place customers interact with your business. Whether you generate enquiries, sell products online or simply provide information, an unexpected website problem can quickly affect sales, customer trust and day-to-day operations.

The good news is that not every website issue is caused by a major technical failure. Some problems are local to your device, while others can be resolved by checking your hosting, domain, SSL certificate or recent website changes. Knowing where to look first can save valuable time and help you avoid making the situation worse.

This guide explains how to diagnose common website problems, understand what may be causing them and decide whether you can safely fix the issue yourself or need professional website support.

At a Glance

• Most website problems can be traced to hosting, domains, DNS, SSL certificates, software updates or recent changes.
• Always confirm whether the issue affects everyone or only your device before making changes.
• Avoid changing multiple settings at once, as this can make diagnosis more difficult.
• Website downtime can interrupt enquiries, online sales and customer communication.
• Many problems can be resolved without rebuilding the website.
• Serious server, database or security issues should be handled by experienced developers.
• Regular maintenance, backups and monitoring help prevent future downtime.

Website Not Working? Start Here

Before logging into your hosting account or changing website settings, spend one minute confirming that the problem is genuine.

Many website issues turn out to be caused by local internet connections, browser cache or temporary network problems rather than the website itself.

Complete this quick checklist

✔ Try opening the website on another device.

✔ Turn off Wi-Fi and load the website using your mobile network.

✔ Open the website in a different browser.

✔ Ask a colleague or friend to check whether the website loads for them.

✔ Use an online website status checker to confirm whether the website is accessible from outside your network.

If the website works everywhere except your own device, the problem is likely local rather than a website failure.

If nobody can access the website, continue through the troubleshooting steps below.

Before You Change Anything

When a website suddenly stops working, the natural reaction is to start clicking through hosting settings, updating plugins or changing DNS records.

Unfortunately, rushing often makes recovery more difficult.

Before attempting any fixes, follow these simple rules.

Record the symptoms

Take screenshots of any error messages and note exactly what happened before the problem started.

Ask yourself:

• Did you install a plugin?
• Did you update WordPress?
• Did you move hosting providers?
• Did you change DNS settings?
• Did you renew your domain?
• Did you install an SSL certificate?
• Did someone edit the website?

Recent changes often provide the biggest clue to the underlying problem.

Avoid changing multiple settings

Test one solution at a time.

If you make several changes together, it becomes much harder to identify which one fixed the issue—or caused another problem.

Be cautious with DNS settings

Incorrect DNS changes can affect more than your website. They may also interrupt business email services, making communication with customers even more difficult.

Unless you understand exactly what each record does, avoid changing DNS entries during initial troubleshooting.

Keep a simple log

Write down every action you take.

If you eventually need professional support, this information can significantly reduce diagnosis time and help avoid unnecessary work.

Why Fixing Website Problems Quickly Matters

A website outage is rarely just a technical inconvenience.

For many businesses, every minute of downtime represents missed opportunities.

Customers may be unable to:

• submit contact forms
• make purchases
• request quotations
• book appointments
• access important information

Meanwhile, marketing campaigns may continue sending visitors to pages that no longer work.

If the outage continues for an extended period, search engines may also reduce how frequently they crawl affected pages until the website becomes reliably available again.

The sooner the underlying issue is identified, the sooner normal business activity can resume.

What Does “Website Not Working” Actually Mean?

The phrase “website not working” can describe many different situations.

Some visitors cannot access the website at all.

Others see error messages.

Sometimes only certain features fail, such as contact forms or shopping baskets.

Understanding which type of problem you are facing makes troubleshooting much easier.

Common examples include:

• the website will not load
• the website is extremely slow
• pages display a 404 error
• visitors see a security warning
• images are missing
• contact forms stop sending messages
• checkout no longer works
• only the mobile version has problems

Each symptom usually points towards a different underlying cause.

Why Won’t My Website Load?

A website may fail to load because of hosting issues, an expired domain, DNS problems, server errors, internet connectivity issues, or recent website changes. The first step is to determine whether the problem affects everyone or only your device.

Seeing a blank screen or an error message can be alarming, especially if your website generates enquiries or online sales. However, not every loading problem means the website itself has failed.

Start by checking whether the website opens on another device or using mobile data. If it does, the issue is probably local to your internet connection, browser or computer.

If the website cannot be reached by anyone, the problem is more likely to involve your hosting provider, domain name, server or website software.

What should you check first?

Work through these checks in order.

1. Has anything changed recently?

Many website problems appear immediately after:

• Updating WordPress
• Installing a new plugin
• Changing themes
• Moving to a new hosting provider
• Editing website files
• Changing DNS settings
• Renewing or transferring a domain

If the website stopped working shortly after a change, you’ve already narrowed down the possible cause.

2. Check your hosting account

Most hosting companies display service alerts or account notifications if servers are experiencing problems.

Look for:

• server maintenance
• suspended hosting accounts
• storage limits
• unusually high resource usage

3. Confirm your domain is active

If your domain registration has expired, visitors may no longer reach your website.

Log in to your domain registrar and confirm that:

• the domain is active
• contact details are up to date
• renewal payments have been processed

Remember that renewing an expired domain may take time to become visible across the internet.

4. Look at the error message

Different error messages point towards different causes.

A “Not Secure” warning usually relates to SSL.

A “404” suggests the page cannot be found.

A “500” points to a server-side problem.

The wording on the screen often provides your first clue.

Why Is My Website Running Slowly?

Slow websites are commonly caused by poor hosting performance, large images, outdated software, excessive plugins, unoptimised code or temporary spikes in traffic.

A slow website is often just as damaging as a website that won’t load at all.

Visitors expect pages to appear quickly. If they don’t, many simply leave without contacting the business or completing a purchase.

Even small delays can affect user experience and reduce conversions.

Common reasons websites become slow

Poor hosting performance

Shared hosting plans can become overloaded when too many websites compete for the same server resources. If your website regularly slows down during busy periods, your hosting package may no longer be suitable.

Large images

High-resolution images that haven’t been compressed are one of the most common causes of slow page loading. Modern image formats and proper optimisation can significantly improve performance without reducing quality.

Too many plugins

Every additional plugin increases the amount of work your website performs. Old, unnecessary or poorly coded plugins can dramatically slow down loading times.

Regular reviews help keep your website efficient.

Outdated software

Older versions of content management systems, themes and plugins may become slower over time while also introducing security risks.

Keeping software updated improves both performance and stability.

Third-party services

Live chat widgets, advertising scripts, analytics tools and social media integrations all add additional requests before a page finishes loading.

While many are useful, too many external services can noticeably reduce speed.

What Do Common Website Error Messages Mean?

Website error messages help identify the source of a problem. Some errors relate to missing pages, while others indicate server issues, permissions or temporary service interruptions.

Understanding what an error message means helps you avoid trying the wrong fix.

Below are some of the most common website errors businesses encounter.

404 Not Found

What it means

The page you’re trying to visit cannot be found.

This often happens after pages are deleted, renamed or moved without updating internal links or redirects.

What you can do

• Check the website address for typing mistakes.
• Test other pages on the website.
• Restore missing pages if they were removed accidentally.
• Create redirects for moved content.

403 Forbidden

What it means

The server understands your request but refuses access.

This may be caused by incorrect file permissions, security settings or access restrictions.

What you can do

• Check whether only one page is affected.
• Review recent security plugin changes.
• Contact your hosting provider if permissions appear incorrect.

500 Internal Server Error

What it means

Something unexpected has gone wrong on the server, but the server cannot identify the exact problem.

This is one of the most common website errors after software updates or configuration changes.

What you can do

• Review any recent updates.
• Check whether plugins or themes may have caused a conflict.
• Restore a recent backup if appropriate.
• Contact your hosting provider if the problem continues.

503 Service Unavailable

What it means

The server is temporarily unable to handle requests.

This may happen during maintenance, unusually high traffic or temporary server issues.

What you can do

• Wait a few minutes and try again.
• Check whether your hosting provider has reported an outage.
• If you planned maintenance, ensure your developer has configured it correctly.

White Screen

What it means

Sometimes called the “White Screen of Death”, this usually indicates a serious software or server error preventing the page from loading correctly.

What you can do

• Review recent website updates.
• Disable recently installed plugins if you can safely access your website.
• Restore a backup if available.
• Contact your developer if the cause isn’t obvious.

Why Does My Website Say “Not Secure”?

A “Not Secure” warning usually means there is a problem with your SSL certificate or secure connection. Visitors may lose confidence in the website and some browsers may display security warnings before allowing access.

SSL certificates encrypt information sent between your website and visitors.

Without a valid SSL certificate, browsers may warn users that the website could be unsafe.

For businesses, this can quickly damage trust.

Common causes

• expired SSL certificate
• incorrect certificate installation
• mixed content (secure pages loading insecure files)
• DNS changes
• hosting migration

What should you do?

First, confirm whether your SSL certificate is active through your hosting control panel.

If the certificate has expired, renew it as soon as possible.

If you’ve recently moved hosting providers or changed domain settings, the certificate may need to be reconfigured.

Avoid ignoring browser warnings, as customers may leave before ever reaching your website.

Could My Domain Name Be the Problem?

Yes. If a domain expires or its DNS records are changed incorrectly, visitors may be unable to reach your website even though the website files are still online.

Your domain name acts as the address people use to find your website.

If that address no longer points to the correct server, the website becomes inaccessible.

Common domain-related problems

• expired registration
• incorrect DNS records
• nameserver changes
• transfer delays
• registrar account issues

Always check your domain status before assuming your website has been deleted.

In many cases, the website itself is still intact—it simply cannot be found.

Could My Hosting Provider Be Causing the Problem?

Yes. If your hosting provider is experiencing technical issues, your website may become unavailable even though your files and domain are working correctly. Server outages, resource limits and maintenance can all affect website availability.

Think of your hosting provider as the building where your website lives.

Even if your website is perfectly built, visitors won’t be able to access it if the building temporarily closes or experiences technical problems.

Hosting-related issues are more common than many business owners realise, particularly on low-cost shared hosting plans where multiple websites share the same server resources.

Signs your hosting could be the problem

You may notice:

• Every page has stopped loading.
• The website was working normally earlier in the day.
• You recently received emails about storage or bandwidth limits.
• Your hosting dashboard shows maintenance or service alerts.
• Other websites on the same hosting account are also unavailable.

What should you do?

Start by logging into your hosting account and checking for service notifications or account warnings.

If your hosting provider has confirmed an outage, there is usually little you can do except monitor updates and wait for service to be restored.

If no outage has been reported, contact their technical support team. They can often identify server-side problems much faster than troubleshooting from the website itself.

My WordPress Website Stopped Working After an Update

WordPress websites can stop working after updates if a plugin, theme or software version is incompatible. Most problems can be traced back to a recent change rather than WordPress itself.

Because WordPress powers a significant share of business websites, update-related issues are among the most common support requests.

Fortunately, many are recoverable without rebuilding the entire website.

Step 1: Think about what changed

Ask yourself:

• Did WordPress update automatically?
• Did you install a new plugin?
• Did you update several plugins at once?
• Did you switch themes?
• Did you edit website files?

If the problem appeared immediately afterwards, you’ve already narrowed the search considerably.

Step 2: Check for recovery options

Many hosting providers include one-click backup restoration or recovery tools.

If a recent update caused the problem, restoring a known working backup may be the quickest solution.

Only restore backups if you understand what data could be lost, particularly on websites that receive customer enquiries or online orders.

Step 3: Test plugins carefully

Plugin conflicts are a frequent cause of WordPress failures.

If you can safely access your website or hosting file manager, disable one plugin at a time and test the website after each change.

Avoid disabling everything at once unless instructed by your developer, as this makes it harder to identify the actual cause.

What If I Use Shopify, Wix or Squarespace?

Website problems on hosted platforms such as Shopify, Wix and Squarespace are often related to domain settings, third-party apps or platform services rather than server configuration.

Unlike self-hosted WordPress websites, these platforms manage much of the underlying infrastructure for you.

That means some technical issues are outside your control.

Shopify

Common problems include:

• checkout issues
• payment gateway errors
• third-party app conflicts
• domain connection problems

If your store suddenly stops working, check whether Shopify has reported a wider service issue before changing settings.

Wix

Wix problems often involve:

• custom domain connections
• DNS settings
• publishing issues
• browser caching

If your website recently stopped appearing on your domain, review your domain connection before rebuilding pages.

Squarespace

Squarespace users most commonly experience:

• DNS configuration problems
• expired domains
• SSL activation delays
• publishing issues

Again, checking the platform’s service status is often the quickest first step.

Why Isn’t My Contact Form Working?

Contact forms can stop working because of email configuration problems, software updates, spam protection settings or server changes. The website may appear normal while enquiries fail silently.

This is one of the most damaging website problems because many businesses don’t notice it until customers start complaining.

Meanwhile, valuable enquiries may never arrive.

Warning signs

You may notice:

• fewer enquiries than usual
• no confirmation emails
• form submissions disappear
• spam filters blocking messages

How to test your form

Complete your own contact form using a different email address.

Check whether:

• confirmation messages appear
• emails arrive successfully
• information reaches your inbox
• submissions appear in your website records, if available

Testing should form part of your regular website maintenance rather than only after problems appear.

Has My Website Been Hacked?

A hacked website may display unexpected content, redirect visitors, become unusually slow or trigger browser security warnings. Professional investigation is recommended if malware or unauthorised access is suspected.

Cyber attacks affect businesses of every size.

Hackers often target automated vulnerabilities rather than specific companies.

Common warning signs

Watch for:

• unfamiliar pages
• unexpected redirects
• browser security warnings
• sudden drops in website performance
• administrator accounts you don’t recognise
• unusual file changes

What should you do first?

Avoid deleting files immediately.

Instead:

• change administrator passwords
• contact your hosting provider
• isolate the website if necessary
• check whether backups are available
• seek professional assistance if malware is suspected

Incomplete malware removal may leave hidden backdoors that allow attackers to regain access later.

Does Website Downtime Affect SEO?

A brief website outage is unlikely to have a lasting effect on search visibility. However, if a website remains unavailable for an extended period, search engines may reduce crawling and eventually remove affected pages from search results until the site becomes consistently accessible again.

Search engines understand that websites occasionally experience technical issues.

Temporary outages happen.

Problems arise when search engines repeatedly encounter inaccessible pages over a longer period.

That’s why resolving website issues promptly is important—not only for customers but also for maintaining long-term search visibility.

If you know your website will be unavailable during planned maintenance, your developer can configure the server to communicate that the interruption is temporary using the appropriate server response. This helps search engines understand that the website is expected to return shortly.

What Should You Tell Customers?

If your website is unavailable, keeping customers informed helps maintain trust.

A short update on your social media channels, Google Business Profile or other communication channels can reassure customers that the issue is already being addressed.

Include:

• acknowledgement of the issue
• reassurance that work is underway
• alternative contact details
• expected updates where possible

A simple, professional message is often all that’s needed until service returns.

How Long Do Common Website Problems Take to Fix?

Some website issues can be resolved in minutes, while others may take several hours or longer depending on the cause. Problems involving hosting, security or databases usually require more investigation than simple configuration issues.

The table below provides a general guide. Every website is different, so actual resolution times will vary depending on the platform, hosting environment and complexity of the issue.

The key is identifying the correct cause before making changes. Guesswork often increases downtime.

Should You Fix It Yourself or Call a Professional?

Not every website problem requires specialist support. However, some issues involve servers, databases or security systems where incorrect changes can make recovery more difficult.

Use the guide below to help decide your next step.

If you’re ever unsure, it’s usually safer to pause and seek advice rather than continue making changes that could affect your website or business data.

How Can You Prevent Website Problems in the Future?

Regular maintenance is the most effective way to reduce website downtime. Keeping software updated, monitoring performance and maintaining reliable backups helps prevent many common issues before they affect customers.

No website can guarantee 100% uptime, but good maintenance dramatically reduces the risk of unexpected failures.

Keep software up to date

Outdated content management systems, plugins and themes are a common source of compatibility and security problems.

Update them regularly, but avoid making major changes directly on a live website without testing first.

Maintain regular backups

Backups provide a safety net if something goes wrong.

Store copies securely and test them occasionally to make sure they can be restored successfully.

Monitor website uptime

Website monitoring tools can alert you if your website becomes unavailable, allowing you to respond before customers begin reporting problems.

Review website security

Strong passwords, multi-factor authentication where available and regular security reviews help reduce the risk of unauthorised access.

Check your SSL certificate

Don’t wait until customers see a browser warning.

Monitor certificate renewal dates and ensure secure connections remain active.

Review hosting performance

As your business grows, your website may outgrow its original hosting package.

Regular performance reviews help ensure your hosting continues to meet your needs.

Schedule routine maintenance

Routine maintenance allows potential issues to be identified before they develop into serious outages.

Many businesses choose a maintenance plan because it provides ongoing monitoring, updates and support without needing to react to emergencies.

FAQ

Why is my website not working?

A website may stop working because of hosting issues, expired domains, DNS problems, software updates, server errors, SSL certificate issues or internet connectivity problems. Identifying whether the problem affects everyone or only your device is the first step.

How do I know if my website is down?

Try accessing your website from another device or mobile network. You can also use an online website status checker to confirm whether the website is unavailable to everyone or only on your connection.

Can I fix my own website?

Many basic issues, such as clearing browser cache, testing contact forms or renewing an expired domain, can often be handled by business owners. More complex server, database or security issues usually require professional support.

Does website downtime affect Google rankings?

Short periods of downtime are generally not a problem. However, if a website remains unavailable for an extended period, search engines may reduce crawling and eventually remove affected pages from search results until the website becomes consistently accessible again.

Should I rebuild my website if it stops working?

Not usually.

Most website problems are caused by configuration, software or hosting issues rather than the website itself. Identifying the root cause is normally faster and more cost-effective than starting again.

Final Thoughts

A website failure can feel overwhelming, particularly when your business depends on online enquiries, bookings or sales.

The good news is that many website problems have straightforward explanations. Taking a structured approach—confirming the issue, identifying recent changes and troubleshooting one step at a time—often leads to a quicker resolution and avoids creating additional problems.

Where issues involve servers, databases or website security, seeking professional support early can reduce downtime and help protect your business.

Regular maintenance, reliable backups and ongoing monitoring remain the best long-term defence against unexpected website problems.
