I'm thinking maybe the problem is $q. It looks like it might not be set to anything at that point (although it depends on the value of $_POST['do'], which I don't know). But I suppose it could be that before it was just an unset value generating a warning, and now something else has used it as a variable (a plugin or included vb code).

That's just a guess, but it looks like $formbit should definitely be an array at that point (unless you have a plugin using hook easy_forms_view_question_start that changes it).
