I cannot connect to my Google calendars
Thunderbird 31.2.0 Lightning 3.3.1 Provider for Google Calendar 1.0.1
Recently my 3 Google calendars displayed the yellow triangles indicating a connection problem. I tried to re-add the calendars using the ical method. That didn't work.
Additionally a blank log in screen appears asking for my user name and password but it's blank.
Please help.
