It just started failing a few days ago: The logs showed an error like this:
[2013-03-06 11:14:05] - [Error] [Google+ - The Shirt List] - -=ERROR=- | PostID: 51068 - TacocaT T-Shirt
and now this:
[2013-03-06 23:46:36] - [Error] [Google+ - The Shirt List] - -=ERROR=- Error: You are not authorized to publish to this page. Are you sure this is even a page? | PostID: 50751 - Zombie Season T-Shirt
Any ideas? Did something change at Google+? Perhaps I should just try to remove it and set it up again?
