My website was hacked today by someone called Haxorsistz. When you typed in my URL you just got a message saying the site was hacked, nothing was deleted, but the Index page was changed. I also noticed the .PHP files in my root directory were deleted.
I thought uploading new .PHP files along with the proper config file would fix the problem, but it didn't. You now get a server error when you type my URL and you get the same server error when you try to access wp-login. I also tried doing a manual update to the latest version of wordpress, but that did nothing. All of my content appears to still be in the proper place, but for some reason it isn't showing up on the internet. Not sure what I can do to get things working. Any help would be appreciated.
