My users are registered into a free account (by default) upon registration, and for that account (usergroup) I have set all the limits in Admin panel (in PhotoPost). I also checked the database and I found the problem - I don't know how to address it though. In pp_usergroups table the id of the free account is "6", but when I checked the pp_users table all my users belong to a group with id=0! In my pp_usergroups table I don't even have a group with id=0. How are my members assigned to a nonexistent member group?
