I fixed it by contacting my host. It ends up that the permissions somehow got changed on that one particular post. Once they changed the permissions, it was fine. I just had to re-upload one photograph. So I’d recommend contacting your host.
Bluehost did the restore on their end. How would I locate it?
I am having this same problem since upgrading to 3.4.1. My stats are also not counting correctly. (The stat bars shows significantly less than the added amounts from referrers and searches.) I look forward to hearing the answer!
