Hey Mitchell,
Thank your for reaching out to us! I’m very sorry about this issue you are experiencing, let me help you with that!
I believe that in your specific case there’s a theme or plugin conflict generating this 500 internal server error.
The next step would be to go through our testing for conflicts procedure (preferably in a staging/dev environment or local install of your WordPress website) and let us know what you find out.
Basically the goal here is to revert back to a bare WordPress installation to see if the problem persists. It also allows us to pinpoint what the cause of the issue is.
I would also suggest you to enable WP_DEBUG and WP_DEBUG_LOG and share with us any messages you see while recreating this 500 internal server error. All WP_DEBUG messages will be stored in a debug.log file in /wp-content/debug.log.
If you have any other questions in the meantime, please let me know and I’ll be happy to assist!
Best Regards,
Patricia
