I've had troubles with an application that randomly (until now) unsets the session variable $_SESSION['editor']. I've hunted through all my code and finally managed to rule out everything else than the following couple of lines.
It unsets the session variable $_SESSION['editor'], but leaving others, like $_SESSION['admin'] untouched. At the first debug, I get "Admin: Y Editor: Y" printed (which is the way I suppose things to be), but at the second debug I just get "Admin: Y Editor:".
I can't find the error though. Any input appreciated!
Best regards,
Anders Thoresson
