Has anyone else seen posts that are mostly, but not entirely, invisible? At present I have one post that I can access only via the notification it generated to my Inbox. When I do, it opens in G+ showing all the relevant data correctly--poster, category, date & time. Oddly though, both on my computer (Macbook, Chrome) and the poster's computer, this one post--and as far as I know, only this one post--is completely invisible otherwise. It does not appear in the listing of posts under that category. Also it does not appear in the listing of posts by that poster--neither when I click on his name nor when I perform a search within the Community. Yet the member does still appear on the Community's list of members, and I have no problems with his prior posts.
I caught the problem because I told students (in a class whose online component is a G+C) to contact me if any of their posts did not show a response from me. Now (because I have reason not to depend on G+), I need to rely more heavily on students to check (which will not work during weeks I don't manage to respond to all posts), and/or I must depend on my Inbox rather than on the Community-place.
In case any Googs might check the actual post, here are the details:
Private Community I own: Arts & Ideas, Renaissance to Modern
Poster: Juventino R.
