There were problems this morning, not quite as you described though. StuartDH did fix something, but people had to clear their internet cache (temporary files) before the fix took effect. You could try doing that.

EDIT: I see Graham posted a reply at the same time as I did! In my case, it was definitely the internet temporary files I deleted, I left the cookie alone. I think that's what other people did too.
