Being that this is the first time, I believe it has been hacked as opposed to defaced. You can see for yourself here.
http://www.publicseye.com the admincp was still accessible as of last night. Being that the board has only been up about a week or so I deleted all files from my host and attempted to reinstall vB. After reinstalling I still saw the message that you see now when clicking on my page, which really confused me. Is my database corrupt now? who knows. But after my reinstall there were some viewing issues with the admincp which I think might have just been an error in files transferring over.
I'm running 3.5.x no modifications other than a few new styles.
Any help you'd be able to provide me would be great!!
