I need help! I have been hacked and how do I restore everything to default please?

I was hacked by 2 people, how do I restore my Darkrp settings to default please and how should I prevent this in the future?

Buy the cake anti-cheat from ScriptFodder, and to restore it, no idea.

Depending on the damage, I recommend reinstalling Dark RP entirely and possibly all your add-ons. There’s no point of using obsolete software, especially when it represents a possible vulnerability on your server.

!cake doesn’t protect against backdoors, abusive admins or leaving mysql passwords in clientside files
