I have been playing around with the site a bit so if anyone is having problems logging in, staying logged in or not being able to log out, this is why. I hope I will have this solved tonight. If I do not I will put all my changes back for the night and re-start in the morning.
EDIT: Session verification fails when trying to log out through the user info block on the portal. Log out is fine if done from the menu bar in the forum. This should be fixed soon.
