Thunderbird/Lightening/Provider Calendar Error
I use Thunderbird with the above addons so I can view various calendars hosted on Google's calendar. Today I've started getting the following error: This calendar <calendar> is momentarily not avaible.
I've no idea if Google is down, if something's changed my password, if the page cannot be found, I've literally got no idea where to start with something that was working fine at 0800 this morning but at 0830, with nothing changing suddenly not working.
Is there anyway I can see a log of what's happening or is there something I can try? Googleing suggests trying to disable offline support, but there is no such box in my options of this.
