== Posting to forums seem to be working, but when I go to my profile to see my list of forum posts, that is blank ==

Change your display name in profile to something different from your username.

== When I try and post in a group or comment/reply to anything in the activity stream, I get the error “There was an error posting that reply, please try again.” ==
