How to Fix the 500 Internal Server Error in WordPress

The 500 internal server error in WordPress can be quite frustrating, causing your Website to become inaccessible and leaving you questioning what went wrong. In this article, we will explore the reasons behind this error and provide step-by-step instructions on how to fix it.

What is the 500 internal server error in WordPress?

The 500 internal server error is a generic error message that indicates something is amiss within your WordPress website. When this error occurs, WordPress is unable to function properly and display content on your screen. However, it's important to note that this error is not as catastrophic as it sounds - it is often caused by a single issue that can be easily resolved.

Common causes of the 500 internal server error

The 500 internal server error can be attributed to broken code in one of three areas: plugins, themes, or the WordPress core. These three components are crucial to the functioning of your website, and any errors within them can lead to the server error. Let's Delve into these causes in more Detail:

1. Broken code in plugins

Plugins are one of the primary causes of the 500 internal server error. Whether it is due to a faulty plugin, a conflict between plugins, or a hacking attempt, broken code within plugins can disrupt the smooth operation of your website. To identify the problematic plugin, it is recommended to deactivate all plugins and reactivate them one by one until the error occurs.

2. Broken code in themes

Themes define the appearance of your WordPress website, and if there is broken code within your active theme, it can trigger the 500 internal server error. Testing different themes, particularly switching to a default theme like Twenty Seventeen, can help determine if the issue lies within the theme itself.

3. Broken code in WordPress core

While it is relatively uncommon, broken code within the WordPress core can also lead to the server error. This can occur as a result of a failed update or an error during the installation process. Reinstalling WordPress can often resolve this issue and restore your website's functionality.

4. Other potential causes

Apart from the aforementioned causes, other factors can contribute to the 500 internal server error. These include issues with file permissions, memory limits, server misconfigurations, or conflicts with other software on the server. Although less common, these causes should not be overlooked when troubleshooting the error.

The importance of backups

Before attempting any fixes, it is crucial to have a reliable backup system in place. This ensures that you have a copy of your website's content and configuration before any changes are made. If you do not already have a backup system in place, it is recommended to prioritize setting one up to prevent data loss in the future.

Contacting hosting support

If you have access to support from your hosting company, this is often the quickest and most efficient way to fix the 500 internal server error. Hosting support teams have extensive experience dealing with this issue and can access server log files to pinpoint the exact cause of the error. They can also remove any problem files and guide you through the resolution process.

Troubleshooting on your own

If you are unable to reach hosting support, or the issue occurs outside of their working hours, there are several steps you can take to troubleshoot the error on your own. These steps involve deactivating plugins, switching to a default theme, and reinstalling WordPress. However, it's important to note that these methods might require technical knowledge and should be pursued cautiously.

6.1 Deactivating plugins

Deactivating plugins can help identify if the error is caused by a specific plugin. By systematically deactivating plugins, you can isolate the problematic one and take appropriate action. It is also recommended to keep backups of both the broken and fixed versions of your website for future reference.

6.2 Switching to a default theme

If deactivating plugins does not solve the 500 internal server error, the next step is to switch to a default WordPress theme. This will help determine whether the issue lies within your theme or elsewhere. Further support may be needed from the theme developer or a professional if the default theme does not resolve the error.

6.3 Reinstalling WordPress

If the previous steps do not resolve the issue, reinstalling WordPress can be a last resort. This process involves accessing the WordPress dashboard, navigating to the updates section, and reinstalling the latest version. Reinstalling WordPress ensures that any core files causing the error are replaced, potentially resolving the issue.

What to do if you can't log into the admin area

In some cases, the 500 internal server error can prevent access to the WordPress admin area, making it challenging to carry out troubleshooting steps. If this occurs, you can attempt to log in using FTP (File Transfer Protocol). FTP allows you to access your website's files directly on the server, making it possible to perform necessary actions even when the admin area is inaccessible.

7.1 Using FTP to troubleshoot

Using FTP, you can download your plugins folder as a backup and then delete it from the server. This action will have the same effect as deactivating plugins and can help identify the issue. Afterward, you can upload your plugins one by one, checking the front end of your site each time, to determine which plugin caused the error. Once identified, you can delete the problematic plugin and upload the rest.

Conclusion

While the 500 internal server error may initially seem daunting, it is usually caused by a specific issue within your WordPress website. By systematically troubleshooting and following the steps outlined in this article, you can pinpoint the cause of the error and implement the necessary fixes. Remember, if at any point you feel overwhelmed or lack the technical expertise, seeking support from your hosting company or a professional is always recommended.
