My staff cannot seem to get logged in at www.fpin.org/institute . Could anyone else running 8.1 or otherwise try logging in (bogus password should work fine) to this site and see if they get an invalid password OR instead get a 404? If I completely bypass WS by sending my WCCP traffic around it the site works fine, but when it goes through WS (even with an exception set) the site just throws a 404 error in the center frame.
I've opened up a ticket with support, but they state there isn't an issue on their end.
