What is a 500 Internal Server Error, and what steps can be taken to troubleshoot it?

A 500 Internal Server Error is a generic error message indicating that something has gone wrong on the server side, but the server cannot specify the exact problem. To troubleshoot this error, you can:

1. Check the server logs for specific error messages that can provide insight into what went wrong.
2. Verify that all server-side scripts (like PHP) are functioning correctly and do not contain syntax errors.
3. Ensure that the server has sufficient resources (like memory and CPU) to handle the requests.
4. Disable any recently added plugins or modules to determine if they are causing the issue.
5. Check for misconfigurations in the web server settings (like Apache or Nginx).
