Rated 5 out of 5 stars

Shortly after I posted this review there was an update to roll back to Version .013. This fixed the problem and hopefully it will stay fixed. I am turning off auto update to avoid future problems before checking on new versions.

I updated Thunderbird today and had to update Lightning. I have been using this sync program for over a year with no problem. Today, my calendar has lost all of my events and I am unable to add any events. Something is seriously wrong and needs to be fixed. I have done with has been suggested - turn off cache, reload the plug in for the sync. Nothing. I am now without a calendar and there seems to be no replacement anywhere. Lightning is now useless to me. Again something needs to be fixed here. Fix the problem promptly and I will rate this plug in a 5 and change this review. Until then stay away from this plug in - and Lightning if you need to sync with Google Calendar.

This review is for a previous version of the add-on (0.16).
