If you try to login when the url doesn't have www. at the beginning, you get this message.
Error: This action is not allowed from an outside domain!!
Action is: login2

At the top, it says "Good Evening *name*," with nothing about PMs. Nothing's broken, I'm just curious about what happened.

When I took "www" out of the site's addess, the site acts as if I'm logged out (but it shows my name in the list of logged-in users). This is corrected if I click "Login", then it will show the login screen in my account's chosen color scheme, meaning I'm already logged in.
