I just started experiencing some very funky (not in a good way) behaviour with Google Calendar (associated with my Gmail account). I can’t get to my calendar directly for some reason and the links on this page don’t take me to a solution. Has anyone else seen this?
Update: I think I figured out the problem. I imported events from Facebook into my calendar and I think the email address embedded in those events somehow confused GCal and I got this message. GCal seems to be working ok now that I removed the two events.
