I've got a very strange problem after migrating from 2.5.7 to 3.5.1 on IIS 7.0.
Whilst the frontend is working without any problems, I can login into my Backend but I only get the White screen of death right after.
I tried "maximum" and "development" for error_reporting, setting
Code: Select all
ini_set('display_errors', TRUE); error_reporting(E_ALL);
Code: Select all
E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED
The problem only exists in the Control Panel, all other Backend sites are working. I also deactivated all third party plugins that could cause problems.
Has anyone of you got a clue what could cause this problem?
