a few hours ago, when login to our vbulletin forum, i get a blank page with message "hacked by Xplo1T
www.prvtzone.net www.belegit.net "
I already checked all php & js files, but none has been changed today, no htaccess files have been changed neither, so i'm guessing it has been done with a kind of redirect parameter in the database - anybody has an idea how i can fix this ? where in the database i should look for a parameter causing a redirect ?
