"File Not Found" requests handling

I just weeded out a bunch of SPAM (seems they are hiting the Blog and other areas outside of the forums) and afterwards went back to the URL and noticed VBSEO is not redirecting back to the home page when the URL is not found.

Running: vBSEO 3.3.0 with security patch

Hello,

that URL is correctly formatted, so it's not a regular "File not found" error, but "Thread with incorrect id", in this case vBSEO just sends additional 404 http header.

You can disable VBSEO_INVALIDID_404 setting in config_vbseo.php to have a normal vBulletin's message "No Thread specified..." displayed.
