I am seeing this in my log as well. Did anyone find out what’s going on there?
This just happened to me as well. A new user was registered, as an administrator. I have never had “anyone can register” checked. I don’t have the WordFence plugin.
I deleted the user right away, and it doesn’t seem like it was used to do anything, but it is very worrying.
Yep, seems to be fixed. Thanks!
Sorry, this is my screw-up; I reverted to version 1.1 and completely forgot to mention it here. I’ve updated it to 1.2 again now, and the problem is back, in both Opera, Firefox, Explorer and Chrome.
