Easy Solutions to Fix Internal Server Error on WordPress

Are you encountering the frustrating Internal Server Error (500) on your WordPress website? This common issue can be caused by various factors, including plugins, themes, or server misconfigurations. However, the good news is that fixing it is often simpler than it seems. In this guide, we'll walk you through the steps to troubleshoot and resolve the Internal Server Error swiftly, getting your website back up and running smoothly.

Understanding Internal Server Error (500)

The Internal Server Error is a generic error message that indicates something has gone wrong on the server but doesn't specify the exact cause. It's like a catch-all error, making it challenging to pinpoint the root issue immediately. However, by following a systematic approach, you can identify and resolve the problem efficiently.

Steps to Fix Internal Server Error on WordPress

1. Check for Corrupt .htaccess File

A corrupt .htaccess file is a common culprit for causing an Internal Server Error. To fix this, access your WordPress root directory via FTP or File Manager in your hosting control panel. Locate the .htaccess file, rename it (for example, to .htaccess_old), and then try accessing your website again. If the error disappears, generate a new .htaccess file by navigating to Settings > Permalinks in your WordPress dashboard and clicking "Save Changes."

2. Deactivate Plugins

Faulty plugins can also trigger Internal Server Errors. To identify the problematic plugin, access your WordPress directory via FTP and navigate to wp-content/plugins/. Rename the "plugins" folder to something like "plugins_old." This action deactivates all plugins at once. Now, check if the error persists. If it disappears, reactivate each plugin one by one until you find the one causing the error. Then, either update the plugin or find an alternative.

3. Switch to a Default Theme

Sometimes, a faulty theme can lead to Internal Server Errors. To check if your theme is causing the issue, access your WordPress directory via FTP and navigate to wp-content/themes/. Rename your current theme's folder to something else (e.g., "theme_old"). WordPress will automatically switch to a default theme. If the error is gone, consider updating your theme to the latest version or contacting the theme developer for assistance.

4. Increase PHP Memory Limit

Insufficient PHP memory limit can also trigger Internal Server Errors, especially if your website has resource-intensive plugins or themes. To increase the PHP memory limit, access your WordPress root directory and locate the wp-config.php file. Add the following line of code just before the line that says '/* That's all, stop editing! Happy blogging. */':

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

Save the changes and check if the error persists.

5. Contact Your Web Hosting Provider

If none of the above solutions work, the issue may be related to server misconfigurations or limitations imposed by your web hosting provider. Contact their support team and provide details about the error, along with the troubleshooting steps you've already taken. They should be able to investigate further and resolve the issue from their end.


Encountering an Internal Server Error on your WordPress website can be frustrating, but with the right troubleshooting steps, you can quickly diagnose and fix the problem. By following the steps outlined in this guide, you'll be able to identify the root cause of the error and implement the necessary fixes to get your website back online in no time. Remember to always back up your website before making any significant changes, and don't hesitate to seek professional assistance if needed.
