I recently upgraded to v1.9.12 from the previous version, at which point my ability to Auto-Post to Google+ died.
I had to ftp back into my site, and manually update the PHP APIs for both Google+ and Pinterest.
This is something that I would like to see automatically take care of itself, given that I would just populate my license key into my WordPress installation.
I would appreciate this being taken on board for future revisions.
Thanks and regards,
