So I don't know what any of this means, I have changed the URL and IP address only.
As for whether it was an affective hack or not, the idiot who has done this has created several hundred back links to the URL which has been picked up by Google, which has created merry hell, as we had a partial notice already!!!
So although I would love to know how and why and by whom this has happened. My main concern is getting the sh1te back links removed. And get to back to concentrating on getting the back links I know were bad in the first place
Such is life though!!!
The google element and bad back links is not really anything to do with this forum post, so sorry for taking my quest for help slightly away from the hacking element...Any further help with the hacking would be most appreciated.
