What Is WordPress Internal Server Error?
A WordPress Internal Server Error is often known as a “500 error.” It’s one of the most common issues WordPress users face, and it usually shows up when something goes wrong on the server. But the tricky part is that it doesn’t tell you exactly what’s causing the problem.
This error can happen for a variety of reasons. Sometimes, it’s a corrupted .htaccess file, or your PHP memory limit might be too low. Other times, it’s due to a plugin or theme conflict. Even incorrect file permissions can cause this issue. Since the error doesn’t point you to a specific fix, it can feel overwhelming at first.
However, most causes are easy to track down and fix with a few simple steps. In the next sections, we’ll guide you through different methods to help you implement a reliable WordPress internal server error fix and get your site back online.
Common Causes Of WordPress Internal Serval Error
There are several common reasons why you might see the WordPress Internal Server Error on your site. One of the main culprits is a corrupted .htaccess file, which can break your site’s connection to the server. Another possible issue is that your PHP memory limit has been exhausted, especially if your site is running a lot of plugins or large files.
Sometimes, plugin or theme conflicts are to blame. When two plugins or a theme don’t work well together, they can trigger this error. Incorrect file permissions are another common cause, and they can prevent WordPress from running properly.
Lastly, there could be a problem with your server configuration, which is something you may need help from your hosting provider to resolve. Understanding these causes can help you narrow down the issue and apply the correct WordPress internal server error fix to get your site working again.
Common Fixes for WordPress Internal Server Error
When you encounter a WordPress Internal Server Error, the good news is that there are several straightforward solutions you can try to get your site back up and running. Let’s walk through some of the most common fixes, step by step.
A. Check for a Corrupted .htaccess File
A corrupted .htaccess file is one of the most frequent causes of the WordPress Internal Server Error. This file controls how URLs are structured on your site, and if it becomes corrupted, it can break the communication between your site and the server, leading to an error.
Here’s how you can fix it:
- Access the .htaccess file via FTP or File Manager:
- First, log into your hosting account and access the File Manager or use an FTP client like FileZilla.
- Navigate to the root folder of your WordPress installation, usually called `public_html` or the folder named after your website.
- Rename the .htaccess file:
- Once you find the file, right-click and rename it to something like `.htaccess_old`. This will disable the current file without deleting it.
- Regenerate a new .htaccess file:
- Go to your WordPress dashboard, click on Settings > Permalinks, and then simply click Save Changes without altering any settings. This action will generate a fresh .htaccess file, and in many cases, this alone can solve the problem.
If the error goes away, you’ve found the issue. If not, there are other fixes to try.
B. Increase PHP Memory Limit
Another common reason for the WordPress Internal Server Error is when your site exhausts its allocated PHP memory. When your site runs out of memory, the server can’t process requests, and the error appears.

C. Deactivate All Plugins
Plugin conflicts are another frequent cause of the WordPress Internal Server Error. If two or more plugins don’t work well together, or if one is outdated, it could trigger the error.
Here’s how to check for plugin conflicts:
- Deactivate all plugins via FTP:
- If you can’t access the WordPress dashboard, connect to your site using an FTP client.
- Navigate to the `wp-content` folder and find the plugins folder. Rename it to something like `plugins_old` to deactivate all the plugins at once.
- Check if the error is resolved:
- If your site loads properly after deactivating the plugins, one of them is the culprit.
- Reactivate plugins one by one:
- To pinpoint the problematic plugin, rename the `plugins_old` folder back to `plugins` and then reactivate each plugin one at a time.
- After activating each plugin, refresh your site to see if the error returns. Once you find the conflicting plugin, you can either update it or replace it with a similar one.
D. Switch to a Default Theme:
Just like plugins, themes can also cause conflicts, especially if they’re poorly coded or incompatible with the latest version of WordPress. Switching to a default theme, such as Twenty Twenty-Three, can help you determine if your theme is causing the WordPress Internal Server Error.
Here’s how to switch to a default theme:
- Access the Themes via FTP:
- Connect to your site using FTP and navigate to the `wp-content/themes` folder.
- Rename the folder of your currently active theme to something like `theme_old`.
- Activate a default theme:
- WordPress will automatically switch to a default theme like Twenty Twenty-Three if your current theme is deactivated.
- Check if the error is resolved:
- If the error is gone after switching themes, your theme was the issue. You may need to update or replace the theme with a more compatible one.
E. Check File Permissions
Incorrect file permissions can also lead to the WordPress Internal Server Error. If WordPress can’t read or write the necessary files, the server may return an error.
Here’s how to check and set the correct file permissions:
- Access your site via FTP or File Manager:
- Connect to your site and navigate to the root directory.
- Set file permissions:
- The recommended permissions are 755 for directories and 644 for files. In your FTP client, right-click on a folder or file, select File Permissions, and set the numeric value accordingly.
- Apply the permissions:
- Make sure to apply these permissions to all subdirectories and files as well.
After adjusting file permissions, refresh your site to see if the error is resolved.
F. Contact Hosting Provider
If none of the above steps work, the issue might be on the server side. It could be something related to your hosting configuration, such as server overload or misconfigured settings.
Here’s what you can do:
- Reach out to your hosting provider:
- Open a support ticket or use live chat to describe the issue. Let them know you’ve already tried the common troubleshooting steps.
- Ask for server logs:
- Sometimes, the server logs will show more details about what’s causing the error, and your hosting provider can help you interpret them.
- Check for server misconfigurations:
- If it’s a server issue, the hosting team can usually fix it for you.
By following these steps, you can apply the correct WordPress internal server error fix and bring your website back online. If the problem persists, don’t hesitate to seek professional help or switch to a more reliable hosting provider.
Preventing Future Internal Server Errors
- Preventing future WordPress Internal Server Errors is all about regular maintenance and smart choices. First, make sure you’re doing regular backups of your site so that if something goes wrong, you can easily restore it.
- Using plugins like UpdraftPlus can make this process simple. It’s also important to keep your plugins, themes, and WordPress version updated to avoid potential security holes or bugs that can lead to errors.
- Next, monitor your server resources. If your site starts growing and using more memory or bandwidth, consider upgrading your hosting plan to handle the increased traffic. This can prevent server overload, which often leads to internal server errors.
- Finally, stick with reliable plugins and themes from trusted sources to reduce the risk of conflicts. By keeping these steps in mind, you’ll minimize the chances of encountering this issue and easily implement the right WordPress internal server error fix if it happens again.
