500 Internal Server Errors can be caused by a number of issues, which can normally be resolved with a bit of troubleshooting.

What to look for:

– If you have made a recent change via FTP, try and undo those changes to see if that resolves the issue

– Check the error_log in your “public_html” directory or login to cPanel and click “Error Log” to see if it mentions a specific error

– Login to your FTP and check the size of your error_log file in the “public_html” directory.  If it’s too large, delete it and see if that resolves the issue.

A Server 500 error will generally look something like this:
