This problem is not solved, I've been running Community builder for a long time, and now suddenly out of the blue (with no changes what so ever to any modules) I suddenly can't log into my site at all, I keep getting the:
Session expired or cookies are not enabled in your browser. Please press "reload page" in your browser, and enable cookies in your browser. Please refresh/reload page before filling-in.
I don't have this joobi, I don't have anything that is supposed to conflict with community builder, and the error just started up randomly. I've turned cache off, nothing, it still does the same thing. I reload the page as instructed, same thing it keeps repeating the error message and refuses to let me on.
This is happening to a lot of people, and it's very spurratic which makes it hard to figure out what's going on, but I know I can't log into my site now. I am logging in through www and not just the domain name without the www.
