Why Is My WordPress Website Not Working? Common Problems and Solutions

If your WordPress website has suddenly stopped working properly, you are probably wondering what went wrong and how to fix it.

A website can appear to break for many different reasons. A plugin update, theme change, PHP version, database problem, hosting configuration or even a small change to the website can sometimes cause unexpected issues.

For a business, this can be more than an inconvenience. Your website may be responsible for generating enquiries, displaying your services, processing orders or giving customers important information.

The good news is that a broken WordPress website does not necessarily mean you need a completely new website. In many cases, the underlying problem can be identified and fixed.

Why is my WordPress website not working?

There is no single reason why a WordPress website stops working.

Some common causes include:

1. Plugin conflicts
2. Theme problems
3. Failed updates
4. PHP compatibility issues
5. Database errors
6. Hosting problems
7. Incorrect website settings
8. Broken or conflicting code
9. Security issues
10. Problems with caching or other performance systems

The first step is to determine what has actually changed or what type of problem the website is experiencing.

Why did my WordPress website break after an update?

Updates are an important part of maintaining WordPress, but an update can sometimes expose compatibility problems.

For example, a plugin may have been working with your existing theme and other plugins, but a new version may introduce a change that conflicts with another part of the website. The same can happen when updating WordPress itself, a theme or the PHP version used by the hosting environment.

If the website stopped working immediately after an update, that timing can provide an important clue when investigating the problem.

However, repeatedly updating, downgrading and reinstalling plugins without first identifying the cause can make troubleshooting more complicated.

Why is my WordPress website showing a critical error?

A WordPress critical error generally means that something has prevented WordPress from executing correctly.

The cause could be a plugin, theme, custom code or another PHP-related problem.

Sometimes WordPress will provide information identifying the component responsible. In other cases, the problem requires checking error logs or investigating recent changes to the website. If you have access to a backup from before the problem occurred, that may also be useful when determining what changed.

A critical error should be investigated rather than simply assuming that WordPress itself needs to be reinstalled.

Why are my WordPress pages not displaying correctly?

A website can still load while individual pages or sections display incorrectly.

You may notice:

1. Text appearing in the wrong position
2. Images not loading
3. Sections overlapping
4. Mobile layouts breaking
5. Menus not working
6. Incorrect spacing
7. Missing content
8. Buttons or forms behaving unexpectedly

These issues can sometimes be caused by CSS or JavaScript conflicts, theme changes, page builder settings, plugin updates or cached versions of files.

The correct solution depends on what is causing the problem. Making random CSS or theme changes can sometimes fix one page while creating another problem elsewhere.

Why is my WordPress website so slow?

A website that technically works can still have a serious problem if it takes too long to load.

WordPress performance can be affected by many factors, including large images, plugins, database queries, hosting resources, external scripts, caching and the way the website itself has been built. Adding more optimisation plugins is not necessarily the answer.

A better approach is to identify where the website is spending time and then address the underlying cause.

For example, the problem could be related to the hosting environment rather than the front end of the website. Alternatively, a particular plugin or database query may be responsible for a significant amount of processing.

Why are my WordPress plugins causing problems?

Plugins are one of the main reasons WordPress is so flexible. They allow a website to add functionality without everything having to be developed from scratch.

However, plugins can also interact with each other.

A website might use plugins for SEO, forms, ecommerce, security, bookings, page building and other functionality. If two components are not compatible, problems can occur. This is particularly important on established business websites where removing a plugin is not always straightforward because other parts of the website may depend on it.

Could my WordPress database be causing the problem?

Yes.

The WordPress database stores important information about the website, including posts, pages, settings, users and other data depending on the plugins installed.

Database problems can result in errors, missing information, unexpected behaviour or parts of the website failing to work correctly.

Database-related problems can be more complicated than a typical WordPress setting and should be handled carefully, particularly when important business data is involved. A backup should be considered before making significant database changes.

Could my hosting or PHP version be causing the problem?

WordPress relies on the hosting environment it runs on.

PHP version, available memory, server configuration and other hosting resources can all affect how a website operates.

A website that worked correctly previously may encounter problems after a PHP version change or hosting configuration change if a theme or plugin is not compatible with the new environment. This is why troubleshooting should not always stop at the WordPress dashboard. Sometimes the cause of the problem is outside WordPress itself.

What should I do if my WordPress website suddenly stops working?

If your website suddenly stops working, avoid making a large number of changes before establishing what happened.

Start by considering:

1. When did the problem first appear?
2. Was anything updated or changed shortly beforehand?
3. Is the entire website affected or only certain pages?
4. Can you access the WordPress administration area?
5. Are customers experiencing the same problem?
6. Are there any error messages?
7. Do you have a recent backup?

These details can make troubleshooting considerably easier.

If the website is an important part of your business, it can also be worth getting assistance before attempting major changes yourself.

Does a broken WordPress website need to be rebuilt?

Not necessarily.

A website can develop problems without the underlying design or content needing to be replaced.

If the issue is caused by a plugin conflict, configuration problem, database error, PHP compatibility issue or another technical problem, it may be possible to repair the existing website. A rebuild may be appropriate in some situations, particularly where an old website has become difficult to maintain or contains extensive technical problems. But it should not automatically be the first recommendation whenever something stops working.

Understanding the existing website and identifying the actual problem is an important part of deciding what should happen next.

When should I get professional WordPress help?

If you are comfortable managing WordPress, you may be able to resolve straightforward content and maintenance tasks yourself.

Professional assistance can be useful when the problem involves errors, code, databases, plugins, hosting, security or functionality that you cannot identify or safely change yourself.

It can also be worthwhile if you have already tried several fixes without resolving the problem.

The goal should not simply be to make the error disappear.

The underlying cause should ideally be identified so that the same problem is less likely to happen again.

Need help with a WordPress website?

I help businesses with WordPress websites that need troubleshooting, maintenance, updates, improvements and technical support.

Whether your website is displaying an error, a plugin has caused a problem, pages are no longer displaying correctly, your website has become slow or something else is not working as expected, I can investigate the issue and determine what needs to be done.

I also work with existing WordPress websites, so you do not necessarily need to start again with a new website simply because your current one has developed a problem. If your WordPress website is not working properly, contact me with details of the problem and what happened before it occurred. If you have an error message or screenshot, including that information can also help with the initial assessment.

Sometimes the right solution is not a new website. It is simply finding the problem and fixing it properly.
