I went through and deleted all my browser history, cookies, temporary files, etc.
Now when I log in, the only parts of the site that actually acknowledge me being logged in are the forums. I cannot access "My Account", etc, it just redirects me to the login page.
I don't know what I did other than delete the existing cookies.
Firefox 3.0.7
