in Vbseo htacess i find :

HTML Code:

# Comment the following line (add '#' at the beginning)
# to disable mod_rewrite functions.
# Please note: you still need to disable the hack in
# the vBSEO control panel to stop url rewrites.
RewriteEngine On
# Some servers require the Rewritebase directive to be
# enabled (remove '#' at the beginning to activate)
# Please note: when enabled, you must include the path
# to your root vBulletin folder (i.e. RewriteBase /forums)
#RewriteBase /
#RewriteCond %{HTTP_HOST} !^www.yourdomain.com
#RewriteRule (.*) http://www.yourdomain.com/forums/$1 [L,R=301]
RewriteRule ^((urllist|sitemap_).*.(xml|txt)(.gz)?)$ vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 [L]
RewriteCond %{QUERY_STRING} !vbseourl=
RewriteCond %{REQUEST_URI} !(admincp/|modcp/|chat|cron)
RewriteRule ^(.*.php)$ vbseo.php?vbseourl=$1 [L,QSA]
RewriteCond %{REQUEST_FILENAME} !.(jpg|gif)$

Hello,

will this htaccess file conflict with your vbseo htaccess (hosted in the forum folder) ?

There should be no conflicts with your root .htaccess.

should i replace the domain.com by my domain name ? and Forums by the name of my forum Folder ?

Yes, domain name and folder name should be modified accordingly (and those two lines should be uncommented by removing a leading "#" character),
