{problem} Can't invite friends? link broken

Hi all!

who to contact, when i click Invite Your Friends, i get this on top of invite page:

Warning: explode() expects parameter 2 to be string, array given in [path]/profile.php(182) : eval()'d code on line 245

When i submit the form, page is loading and loading.. and i get 404 in the end.

...
Also, when I go to "User CP" link i get a white page with "database error" message.

Also noticed that forum was down most of the day, for maintenance.
Was it some kind of attack ?

I have fixed the User CP page problem, the above problem I am working on
