This is not fixed or has resurfaced, at least for me. I'm only able to log in by finding somewhere with a Remember Me box. The login at the top of the home page, appears to work, but redirects back to the home page where it appears I have not logged in, except that I appear in the Online Users list.
I've tried multiple computers and browsers. It's not inconceivable my ISP could have something wrongly cached.
You are actually logged in then, if you click any of the threads in the Recent Threads (or any link at all) and then just go back will find yourself logged in on the index page as well.
