Before I start, I saw the same issue here https://premium.wpmudev.org/forums/topic/not-importing but as it was resolved, I decided to start a new post.
As the title suggest the google+ plugin isn’t importing posts from my Google+ page.
I set up the keys and got authenticated and all that jazz but not posts are showing. I tried displaying them as a widget and had the same issue.
As with the post mentioned above I don’t see any test button.
I have downloaded and installed the file given without any luck.
Any help would be great.
