Last year we lost all media records from early May until the end of August. Our server host deleted them and my backup files couldn't be restored. Within every wiki post that had one of these deleted media files, mostly pictures, a box with an X shows up instead of the picture. We have finally gotten around to fixing this problem. However, I discovered many media records that, instead of the Wiki title showing up under Uploaded To in the Media on the dashboard, say Private Post. So who CAN see a 'Private Post". I am the Super User and if I can't see these, who can? dahhhhh. See attached screen shot.
So I tried to delete several of them. I got the message that I wasn't allowed to do that. (see attached screenshot). Again, I am the Super User Admin. No one should have rights higher than mine. I checked the Users tab and the 4 named Admins are correct, and I AM the Super User.
Additionally, there are OVER 4700 identical posts in my database by this user, Guest1. Every one has, as it's contents, a message about it's membership. I checked it's membership and it is a "Contributor" as all our registered users are. These 4700+ database entries were created constantly over time since we started using WP. They started in October 2014 and ended in late April of 2015. However, they are not Wiki posts nor are they blog posts. We activated the Wiki plugin from the very beginning of our WP use, since our site is a Wikipedia of all things skydiving.
Soooooo, I tried to delete this user. I have deleted users before. It always worked. I can't delete this user. Get an error message.
I am attaching some additional screen shots showing you what I got when I tried to delete all the 'Private Post' entries in the media folder. Then a screen shot of what I got when I tried to delete the user Guest1. And a screen shot of a bunch of the database records by Guest1.
Thanks in advance for your assistance.
