It is on all of my devices. I can't open iCal in the browser. Says something went wrong with iCal.

How do I reset this and get rid of the error. Annoying.

ical sync error Hi, after the google outage of some days ago, that made appointments disappear, now I have an error with syncing the google calendars (with an ! sign beside the account list in ical. The error (in italian) says "an unexpected error occurred with the request (Domain CalCalDavErrorDomain / Error 14). I tried disabling/enabling the account in system pref and emptying the /calendars folder, but to no results (all the changes are temporary). If I put an event in the google web interface (or in other google syncing apps as BusyCal ) the event is reported in Ical, but not the other way round. Any suggestions?
