Sorry, while it may be true; we have regulations and a TOS to follow here.
Unless we can get some clear truth that this site has actually been hacked, and that it is okay to hack it back to it's original condition from the site admin, we can not help you.
We can not take part in illegal activities here. Now, you should also keep in mind that you are posting on a forum that is publicly available, and asking people to help you hack a site. You should be cautious, and not do such things anyways.
If you're not willing to learn, no one can help you. If you're determined to learn, no one can stop you.⠠⠵
The absence of evidence is not evidence of absence.
I can explain it for you, but I can't understand it for you.
