I don't know if this is all part of the same problem but I have noticed that when I pull up a user profile, where it used to say "viewing X" or "Private messaging" or whatever that user was doing over in the upper right corner, everyone says "offline" even when there green dot is clearly lit in the forums and they appear to be actively posting.
At first I thought maybe I was catching users as they went offline but after it continued to happen I thought there may something wrong.
I can submit a trouble ticket if you would like.
