What is your intention with this statement? This looks superfluous to me. This requires register_globals and is in fact deprecated in PHP 5.3
Why this user and no one else? Since this is a server-side message then I would have to assume that no one has tried the exact same steps that this user has tried.... logging in again as soon as the user has logged out. I'm guessing that the session has not been completely reset.
