I would login to cpanel > click "Select PHP Version", click "Switch to PHP Settings" and make sure display_errors is ON and that error_reporting is set to E_ALL
** MAKE SURE YOU APPLY & SAVE THE SETTINGS **
Then reload your page to see any errors. You should generally get an error...
Don't forget to revert settings after
