WEBSITE HACKED!! NEED HELP!
Basically after moving to a new VPS server, my Vbulletin login process just continued to LOOP, so I would log in, it said THANK YOU, then it logged me out. Thinking there was a problem somewhere with PHP, and after days of trying different things, Vbulletin support and I sifted through the access logs and figured out my site was infected somehow with the "Shell by ORB" malware which is infecting certain files, some which I have ferreted out some which I can not find, and are in turn rewriting htaccess files, and doing other things to cause blank/white pages out of my php files.
Job completion and release of funds is completely incumbent upon eradicating this threat from my server.
