I have no idea why it works, but by my posting this you should be able to tell it works.

When you login, go back to the main forums by pressing back a page. It will still show you as logged off, but for some reason when you click on a topic you are then logged in. You are able to post and and enter restricted areas as normal after that.

[edit] Still not perfect, as after you view a post it still shows it as new.

Also, this may not work for everyone, and stay patient.

I think it's fixed now... or its intermittently working for me.
Interesting

It is fixed.
