I reasantly went over to 3.3 and yes i know is rc and i should have waited :( Anyways i got a wierd problem were i can't load 2 portals for some reason.  I;m searching the forums as we speak just as both portals have about 200 users am worried am going to loose them. Is wierd as i can get to other portals on the same system just not these 2.

The error in the event log as i can get in via one of the other portals is.
