I'm also having a similar problem. The 404.php simply redirects to the front page of the forums/index.php regardless of the link. The script doesn't seem to be seeing the URI request.
I assume it is because of the old IPB url versus the new VB url I'm using. I'm trying to forward to my current test environment. (IP and urls changed to protect the innocent.)
Old IPB link:
http://mysite.com/forums/index.php?showtopic=2400
should translate/forward to
New VB link:
http://192.168.2.1/~mysite/forums/sh...ad.php?t=47000
I assume the script is having trouble using an IP + ~home directory style link? Is that the issue? Turning on debug shows no results, so it's obviously not seeing the urls.
Any ideas? Appreciate any help/info.
