How to Fix WordPress Internal Server Error

If you’re a WordPress website owner, you know how frustrating it can be to encounter the dreaded “Internal Server Error.” This error can disrupt the functionality of your site and leave you scratching your head for a solution. But fear not! In this article, we’ll walk you through the steps to fix the WordPress Internal Server Error and get your website back on track.

Step 1: Check Your Plugins

One common cause of the Internal Server Error is a conflicting or poorly coded plugin. Start by deactivating all your plugins and then gradually activating them one by one. After activating each plugin, check if the error reappears. This process will help you identify the problematic plugin, and you can either update it, replace it with an alternative, or seek support from the plugin developer.

Step 2: Review Your Theme

Sometimes, the theme you’re using may be the culprit behind the Internal Server Error. Switch to a default WordPress theme like Twenty Twenty-One and see if the error persists. If the error goes away, it’s likely that your previous theme has compatibility issues or a corrupt file. You can then contact the theme developer for assistance or consider using a different theme.

Step 3: Increase PHP Memory Limit

WordPress relies on PHP to function, and insufficient memory can trigger the Internal Server Error. You can increase the PHP memory limit by editing your wp-config.php file. Add the following line just before the “That’s all, stop editing!” comment:

define('WP_MEMORY_LIMIT', '256M');

This increases the memory limit to 256 megabytes. Save the file and check if the error persists.

Step 4: Check .htaccess File

Your site’s .htaccess file could be causing the Internal Server Error. Rename the file to something like .htaccess_backup and then try accessing your site. If the error is gone, create a new .htaccess file by going to Settings > Permalinks in your WordPress dashboard and saving the settings. This will generate a fresh .htaccess file.

Step 5: Contact Your Hosting Provider

If none of the above steps resolves the issue, it’s time to get in touch with your hosting provider. The Internal Server Error might be caused by server misconfigurations or resource limitations. Provide them with the details of the error, the steps you’ve taken to troubleshoot, and any other relevant information. They should be able to diagnose the problem and help you fix it.


Experiencing a WordPress Internal Server Error can be frustrating, but with the right steps, you can resolve it and get your website running smoothly again. Remember to check your plugins, review your theme, increase the PHP memory limit, review the .htaccess file, and if needed, seek help from your hosting provider. By following these steps, you’ll be well on your way to a error-free WordPress experience.

Now that you have the tools to fix the WordPress Internal Server Error, you can confidently keep your website up and running without any hiccups. Happy website managing!
