I'm having the same problem that GhostOfMatrix has, every time I try to go to some profile it shows me a blank page. It happens in other users profiles and in my own.
i can get to my dashboard, but not to my profile or other's profiles. the same message appears. also, the second message only appears when i click the reload button it gives you, not when i click the actual refresh button that is in the top left part of the browser.
it started today, i think. it might have happened yesterday, but i didn't go to my friends/followers page yesterday, so i don't know. (but i don't think so)
Well it seems to me that the User Profiles are getting a huge update because this has been going on all day. Plus I can visit all other sections of the beta fine.
I found no problems with the games. But since yesterday morning when I woke up the beta hasn't worked. It's 1:38 PM right now and it still doesn't work.
