I administer a number of WordPress-powered web sites.
One of these sites is new, and has been running untouched since it was set up a month ago. Today, I tried to log in, but was unable to do so - all my login attempts were rejected.
After some investigation, I found out that the
wp_users table was missing. All other tables were present, and the blog was fully functional.
None of the entries in the database, nor any of the files suggest that there has been any kind of hacking going on.
I'm due for vacation tomorrow, and this leaves a bit of a worry as I'm the only person taking care of these sites. I've altered all the passwords, of course, and I might do a reinstall of the code base, but I'd like to know whether there is any common bug that could have caused this?
The WP version running is 3.4.1. Noteworthy installed plugins include WP Super cache, All in one SEO pack, and User Photo.
