Strange Re-Direction

I'm running IIS with vbSEO and I'm having some problems getting it working. For some reason, links to threads give 404's and redirect from

HTML Code:

www.livingreefs.com/forums/introduce-yourself/2985-hello-all.html

to

HTML Code:

www.livingreefs.com/introduce-yourself/2985-hello-all.html

Viewing the forum as www.livingreefs.com/forums/introduce-yourself works fine to view them if I manually type it in, otherwise it also tries to redirect it without the /forums part.

Please try to manually define your web documents root folder in config_vbseo.php file:

PHP Code:

      define('VBSEO_CUSTOM_DOCROOT',         'c:/path/to/webroot');
