I have tried following the how to at google calendars but no matter what I enter for my calendar ID I get this
An error was encountered preparing the calendar located at https://www.google.com/calendar/dav/[bunch of numbers-letters here]/events for use. It will not be available.
Tried it in both Lightning extension for Thunderbird and stand alone Sunbird
Error Number : 0x80004005
[Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [calICalendar.uri]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: file:///usr/lib/sunbird/components/calItemModule.js -> file:///usr/lib/sunbird/js/calCalendarManager.js :: cmgr_createCalendar :: line 536" data: no]
Any help appreciated
