hello to you! yesterday there was a user online named "alex" although there are only two users: the admin and another named mark. i do not allow registration and comments are also off. so i don't know where this alex comes from. he's even not shown in the userlist. is this an illegal hack?
i updated from wp 2.0.3 to 2.0.4 two weeks ago using the update-kit. yesterday i changed password, but today in the morning he was online again.
i am really worried because i feel that my website is not longer secure at all.
what can i do to find out where wp gets this name from, when it is not in the userlist?
how can i find out if this person changes something on my website?
i would be very happy if there'd be a help outside!
