The Admin Page Is White Only

I entered the correct user and password, but all that followed was a blank white color. I was really confused as to what to do next. Please help me!

Hello

Did you try development mode ?

In config.local.php set

ini_set('display_errors', 1);

and in file config.php please find "DEVEL" and replace

//define('DEVELOPMENT', true);

on

define('DEVELOPMENT', true);

and next refresh page

Best regards

Robert

Did you check server error logs for new records?
