I'm nervous because I've been hacked recently...
A security plugin I have says someone from a different IP than mine deleted several posts with post IDs that I didn't create. I see no evidence of this in my WP admin so I went into phpMyAdmin to see what I could find. What I found was none of the deleted post IDs but posts in the same post ID vicinity (i.e.. higher numbers than the last post I ever created) and they appear to be coming from NextGen, but I don't understand their purpose. I want to find out if they are legit.
See the screen shot of my phpmyadmin:
PS. I haven't added anything to my NextGen galleries in over a year.
Thanks for your time.
