If you’ve ever encountered the frustrating Internal Server Error in WordPress, you’re not alone. This common error can disrupt website performance, blocking access for both visitors and site owners alike.

Here’s a comprehensive guide to identifying, diagnosing, and Fix The Internal Server Error in WordPress Easily without breaking a sweat.

What Is an Internal Server Error in WordPress?

An Internal Server Error indicates that something has gone wrong on the server, but the server cannot identify the exact cause. Unlike other errors like the 404 Not Found or 403 Forbidden, this one doesn’t specify a problem, making it a bit tricky to troubleshoot.

Common Causes of Internal Server Error

The error could be triggered by various underlying issues. Here are some of the most frequent causes:

• Corrupted .htaccess File
• Memory Limit Exhaustion
• Plugin Conflicts
• Theme Issues
• Corrupted Core Files
• Issues with PHP or MySQL

By identifying the probable cause, you can better apply a solution that matches your issue.

How to Fix the Internal Server Error: Step-by-Step Guide

Step 1: Check and Rename Your .htaccess File

The .htaccess file controls how URLs are structured on your WordPress site. If it’s corrupted, renaming or replacing it can resolve the issue.

• Access Your Site via FTP – Use an FTP client like FileZilla to access your site files.
• Find the .htaccess File – Locate the .htaccess file in the root directory (often under /public_html/).
• Rename the File – Change the name to something like .htaccess-old.
• Refresh Your Site – Check if the site loads without the error.

If renaming resolves the error, go to Settings > Permalinks in your WordPress dashboard and save changes to regenerate a fresh .htaccess file.

Step 2: Increase PHP Memory Limit

Insufficient memory allocation can also trigger the internal server error. Increasing the PHP memory limit can fix this.

• Access wp-config.php File – Through your FTP client, locate and edit the wp-config.php file.
• Add Memory Limit Code – Add this line:
  • define('WP_MEMORY_LIMIT', '256M');
• Save and Refresh – Save the file and check if the error persists.

Step 3: Deactivate All Plugins

Plugins can conflict with each other, causing errors. Here’s how to determine if a plugin is the culprit.

• Go to Your Plugins Folder – Access the wp-content/plugins folder through FTP.
• Rename the Plugins Folder – Temporarily rename it to something like plugins-old.
• Check Your Site – If the error is gone, a plugin is likely causing the issue.
• Reactivate Plugins One by One – Rename the folder back and reactivate plugins one at a time to find the problematic plugin.

Step 4: Switch to a Default Theme

If a plugin isn’t the issue, your theme might be.

• Change to a Default Theme – Go to Appearance > Themes and activate a default theme like Twenty Twenty-One.
• Refresh Your Site – If the error disappears, your theme is the problem.
• Update or Replace Your Theme – Update or replace the faulty theme to resolve the issue.

Step 5: Repair Corrupted WordPress Files

Sometimes WordPress core files get corrupted, especially during updates.

• Download a Fresh Copy of WordPress – Go to wordpress.org and download the latest version.
• Replace wp-admin and wp-includes Folders – Using FTP, upload new copies of wp-admin and wp-includes from your downloaded copy.
• Check the Site – This often restores the site without disrupting content or settings.

Step 6: Check for PHP or Database Errors

Server-side issues such as PHP configuration errors or database issues may cause this error.4

• Enable Debugging in WordPress – Add the following code to wp-config.php to activate debug mode:
  • define(‘WP_DEBUG’, true);
  • define(‘WP_DEBUG_LOG’, true);
• Review Error Log – Check the error log in wp-content/debug.log for specific issues.

Step 7: Contact Your Hosting Provider

If none of the steps above work, the issue might be on the hosting side. Hosting providers often have access to server logs that can reveal the root cause. Contact support for assistance with:

• Server Configuration Issues
• Firewall or Security Blocks
• Bandwidth or Traffic Spikes
