Why can't users enlarge the avatar when they click on it ? As far as I understand they are automatically set to very small pictures in the database so you can't even use them as a profile picture anymore.
Before I could adjust them as admin before activating the profile, now it doesn't work anymore.
And I also can't edit them anymore after the profile has been activated. I remember that in a former version the avatars were stored in the database in their original size users uploaded them.
