The below is even more convoluted when you have ad-blockers installed: then the G+ integration won’t even appear and the behaviour differs between classic G+ and current G+.
So here are the steps:
- Remove the WordPress link from https://security.google.com/settings/security/permissions
- In your blog settings (for me that’s https://wordpress.com/sharing/wiert.me) remove the G+ integration; do this in a Chrome incognito Window if the G+ integration is not visible
- At the same page re-add your G+ integration and follow further steps at https://jetpack.com/support/publicize/google/#reconnecting
I have good news!
A few weeks ago, Google+ made some changes to their API. In doing so introduced some issues with Publicize. The module still worked, but the updates posted by the WordPress app on your Google+ Profile or Google+ Page were only visible to you.
In the past few weeks, we’ve worked with Google+ to start using a new API. That API works just like the old one, with one exception: publicized posts are now public. You can’t change the visibility of publicized posts to “My Circles”, or anything else.
If you’re happy to have Publicize publishing public posts to your Google+ Profile or Page, you can follow the instructions below to delete your old connection, and then reconnect your Jetpack site to your Google+ account:
I hope this helps.
