How do I check my server error logs to diagnose a 500 error?

The location of error logs varies depending on your hosting provider and server setup. Common locations include: /var/log/apache2/error.log (for Apache), /var/log/nginx/error.log (for Nginx), or within your hosting control panel (cPanel, Plesk, etc.). These logs will often contain more detailed information about the error, such as the specific file and line number causing the problem.
