Hello,

Please check yout server's php error logs and let me know the error details so that I can suggest.

If you are not sure about server error logs, you can try to enable app logs by chainging the log_threashold to 1 in the app/config/config.php and then open the page again to produce errors. Lastly check the latest log file in the app/logs/ folder.

Thank you

These are the errors I found in metric, error in cpanel
