Hello guys, I recently updated our forum from 4.0.12 to 4.0.13 without any errors, durring the installation. But when I try to access my admin panel, It takes me to the Sign In.
There it asks me for the Username, Password and Authentication code. After entering the authentication code, it forwards me to a blank page... .
What can be the problem? Before updating to this version, I could login to the admin panel. Is there a workaround how to skip this authentication code or a fix... I have to enter the admin panel urgently. Thanks in advance
