What does this iCal error message mean?
For some reason the message "URL https://caldav.calendar.yahoo.com/principals/users/name@rogers.com///caldav.calendar.yahoo.com/principals/users/name@rogers.com/" keeps popping up along with the notification that http error 404 has occurred. iCal stll seems to work. Any clues?
