Oops then the username got deleted from database!

Is it true that both jen and admin don’t work either in wp or bbpress?

If yes then you may have to add that to database via some SQL query or register again. But if you register again it will be registered as normal user and you won’t have admin rights, since there is no admin present so who will assign this new user, the admin powers.

Register as some username xyz and look in the userlist the entries that exist wheather or not admin/jen is listed.
