Can't Log In to Unity Forums

This is different than previous log-in problems I’ve had. I get the login screen and it looks like it logs me in, my name shows at the top of the window, but then the window immediately refreshes and my name’s gone and I’m logged out again. No problem logging in here (obviously) nor in the Asset Store, just the forums. Same thing in Safari and Chrome.

This is getting to be a problem. Fortunately, I can still log in from my iPad, but it makes copying from Unity a bit awkward. I can’t seem to do anything there without logging in, so I’m kind of stuck. Is there any way to report this to whoever’s running the forum?
