I believe this should work on Vanilla 1.1.10Login to phpmyadmin and find the table "GDN_User". You'll need your UserID. Then go to GDN_UserRole, find your UserID and change your role ID to Administrator role (whatever you set it as in GDN_Role). Let me know if that helps or if you want PM me.
The topic prefix says [FIXED] so did you figure it out?
