A critical error has occurred.
Request is not available in this context

Good times.  I apologize if this has been addressed in an earlier thread.  I've attempted to find a thread on this, but unfortunately, this particular occurance is a little different than others I've seen.

This happens to random people, at seemingly random times.  It started happening yesterday, and no major site upgrades, outtages, or... well ... anything has happened between a week ago and now. 

Yesterday, I got a report of about 6 of our regular rank guys couldn't see the forums while logged in.  One of them created another account in an effort to fix the bug from his end (IE read the forums again) and the new account worked.  During this period of time, my 2 administrator accounts (regular and a test) were able to see the forums just fine with no errors.  Also, our higher ranked guys could see at as well.  (The ranks have to do with members vs officers vs leader/admin)

I attempted to work on the error for a few hours, but to no avail.  I then had to log off, and by the time I got back online to check it about 15 hours later, said error had all but disappeared, and everyone could view the forums just fine. 

Today ... up until about half an hour ago, everything was just peachy.  Now, my personal admin account is getting this error, but upon logging in and checking two of the guys affected yesterday by this, they're working just fine.  My test admin account also works. 

I am completely mindboggled by this, as there doesn't seem to be any rhyme nor reason for why this error keeps coming up.  I'm both kind of amused and kind of worried about this, as there's a fair chunk of things posted on our forums that I don't really want to lose ...

To my knowledge, we're using a very recent build of dotnetnuke ... as the site itself has only been up for about 6 months or so.   

One thing that maybe worth mentioning.  My account used to be at a host level until the other admin basically bumped me down to administrator access ... he's evidentally doing something with a new portal that he doesn't want me or anyone else seeing yet.  Is it possible that he's done something odd that is causing this?  Any help would be appreciated! :)
