HTTP ERROR 500 - Website Temporarily Unavailable Print

If you’re seeing the message:

This page isn’t working
your-main-domain.com is currently unable to handle this request.
HTTP ERROR 500

it means your website’s server encountered an internal error and couldn’t complete the request.

Common Causes

A 500 Internal Server Error typically occurs for one of the following reasons:

1. Incompatible PHP version — Your website’s code may require an older or newer version of PHP.

2. Outdated or faulty WordPress plugin or theme — Plugins often cause conflicts that prevent your site from loading.

3. Corrupted .htaccess file or missing core files — Configuration errors can break the site’s functionality.

4. Exhausted server resources — Excessive memory or CPU usage can temporarily overload your hosting account.

Step-by-Step Troubleshooting

1. Adjust the PHP Version

   • Log in to cPanel.

   • Go to MultiPHP Manager (or Select PHP Version, depending on your host).

   • Choose your domain and switch to an older PHP version (for example, PHP 7.4).

   • Wait a few minutes, then refresh your website.

   • If the issue persists, try a newer PHP version (for example, PHP 8.1).

2. Check Your WordPress Plugins

   • Access File Manager (in cPanel) or use FTP.

   • Navigate to the folder:
     /public_html/wp-content/plugins/

   • Temporarily rename one plugin folder (e.g., plugin-name_disabled) to deactivate it.

   • Refresh your site to see if it loads.

   • Repeat this process for each plugin until the website works again — the last one renamed is likely the cause.

3. Optional: Check the Error Log

   • In cPanel, open Errors or Error Log.

   • Review the latest entries for detailed error messages that pinpoint the problem file or plugin.
