yesterday I went to my WORDPRESS-blog to look up a post, I did not login. Two of my pages ("Bewegung" and "Entspannung") could not be found. I logged in and found, that it had been deleted. I recovered it, published it again and everything seemed to be allright. Only some hours later the same pages again could not be found. This time both had been set on "draft". I again could recover it.
I use the BackWPUp Plugin and the W3 Total Cache Plugin.
There had been someone on that blog with me as an admin. But I deleted this admin adress some days before.
Today I changed my password as well as my email-password and hope that the problem will be solved.
Nevertheless I would very much like you to check wether and how my account has been hacked.
The German WordPress forum supposed my account may have been hacked.
