Hi. Am having problems with Google Calendar sync with the Calendar add-on. "Failed to read 'quotaExceeded' from chrome://gdata-provider/locale/gdata.properties." is the error message that I'm getting. Have about 13 calendars enabled which are currently not reading. Turned off and on cookies, made calendars read-only and back to normal. Only thing that I haven't done is to delete a calendar and to reenable it.
