How to Fix Error Code 500 on VPS and Dedicated Servers

The 500 Internal Server Error (often called Error Code 500) is a common issue website owners face, especially on VPS and Dedicated. This error usually occurs when the server cannot complete a request due to configuration issues or mismanagement. If you’re facing this error, don’t worry. This guide will effectively walk you through how to troubleshoot and fix Error Code 500 Error Code 500 on VPS and Dedicated Servers.

Causes Error Code 500 on VPS and Dedicated Servers

Misconfigured .htaccess File

The .htaccess file is a configuration file used by your server. If this file contains errors or conflicting code, it can cause the 500 Internal Server Error. To troubleshoot, check for errors or misconfigurations, and test by renaming the file to .htaccess.old. Reload your page to determine if this resolves the issue.

Incorrect File Permissions

Incorrect file and folder permissions are another leading cause of Error Code 500. Files and folders should have permission settings of 755 or lower. Any files set to 777 or 666 can cause the server to throw a 500 Internal Server Error. Make sure your files are correctly configured for security and functionality.

Handler Configuration Issues

When using a temporary URL (e.g., 78.64.23.422/~cPanel), the system may use FastCGI, which could require a handler change. In such cases, make sure that the handler is set to suPHP in the WHM (WebHost Manager) settings to prevent Error Code 500 from occurring.

1. Check .htaccess File for Errors:
   • Rename the .htaccess file and reload your website to check if the issue persists.
   • Fix any errors in the file if necessary.

4. Review Server Logs:
   • Check error logs for more detailed information on the root cause of the error.
   • Use this data to refine configurations further.

Additional Troubleshooting Tips
