When the 5.04b announcement went out, I did an svn up to update my Typo installation. The main blog renders fine (http://blog.peekle.net/) but I can't log in to the admin. I put in my login and password, but when I hit "Login" the login page just refreshes. If I look in the log, I can see a new session being created and the admin/dashboard action being redirected to accounts/login; after I put in my credentials, I can see it processing them, and they all pass through just fine, a cookie gets set in my browser with the correct session ID, and Typo redirects to admin -- which promptly redirects back to accounts/login again.

I did the usual thing after an svn up breaks Typo, which is to wait a few days and up it again. No dice there.

I notice the authenticity_token stuff is new, and I gather that's a new Rails feature, but I've no idea what it's all about.

Anyone ever seen this, or have any advice on where to look? Thanks for any help anyone might be able to give.
