my site been hacked?
Using Jamroom
Your server has been hacked into. You need to change all your server passwords and (ideally) restore from a backup before you were hacked.
If your server company does not have backups, change server companies.
Its a difficult situation. You're going to need to try to figure out what changes they made and undo those changes.
You'll also need to figure out how they got in to make those changes then block that hole.
Since you don't know whether the hole was in the server side script, or jamroom, or another script on the server there are lot of places to look for the hole.
It could take a lot of time, or if you hire someone could cost a lot.
