How to Fix Internal Server Error (500) on Your Website

The dreaded “500 Internal Server Error” is one of the most common and frustrating problems for website owners. It’s a generic error that means something went wrong on the server, but the server can't specify exactly what the issue is.

Thankfully, there are several proven ways to identify and fix the cause—especially if you have access to cPanel.

What Causes a 500 Internal Server Error?

- Corrupt or misconfigured .htaccess file
- Incorrect file or folder permissions
- PHP memory limit exceeded
- Faulty plugins or themes (in CMS platforms like WordPress)
- Server misconfiguration or missing files
- Syntax errors in scripts

Step-by-Step: How to Fix It

1. Check the Error Logs

If you’re using cPanel:
Go to Metrics > Errors
Look at recent error messages with timestamps
Identify the script, file, or path mentioned

This is often the fastest way to diagnose the issue.

2. Rename or Fix the .htaccess File

A broken .htaccess file is one of the most common culprits.

Go to File Manager > public_html
Locate .htaccess and rename it to .htaccess_old
Try reloading your site

If it works, the file was the issue. You can regenerate it manually or let your CMS create a new one.

3. Adjust File and Folder Permissions

Incorrect permissions may prevent the server from accessing essential files.

Files should have 644 permissions
Folders should have 755 permissions

Use File Manager to right-click and select Change Permissions.

4. Increase PHP Memory Limit

If your site exceeds the memory limit, it can trigger a 500 error.

Go to Select PHP Version > Options
Increase memory_limit (e.g., to 256M)
Or, edit .htaccess or php.ini and add: php_value memory_limit 256M

5. Disable Plugins or Themes (WordPress Users)

Rename the plugins folder in wp-content to plugins_old
If that doesn’t fix it, try renaming your active theme folder

This helps isolate whether a plugin or theme is causing the issue.

6. Restore from Backup

If recent changes caused the issue, and you have a working backup:

Go to Files > Backup in cPanel
Restore website files and database to an earlier point

7. Contact Hosting Support

If you can’t find the problem or error logs are empty, reach out to your hosting provider. They can check deeper server logs and help resolve the issue.

Final Thoughts

A 500 Internal Server Error can seem mysterious, but it's usually caused by a fixable misconfiguration. With cPanel tools and a bit of investigation, you can often resolve it in minutes.
