Lets give a basic layout of the site: Wordpress installed in the html root VBulletin installed in a /forum subfolder The problem: When typing in the address to the forum, if you do not put in the trailing / the URL is rewritten to http:// instead of www. Wordpress has its own .htaacces file in the html root and vbulletin has its own ,htaacces file in the /forum folder. This is the current vbulletin htaccess file AuthName http://www.fortresstraining.com/forum/ Options +FollowSymlinks RewriteEngine on rewritecond %{http_host} ^fortresstraining.com/forum/ [nc] rewriterule ^(.*)$ http://www.fortresstraining.com/forum/$1 [r=301,nc] Options +FollowSymLinks RewriteEngine on RewriteCond %{HTTP_HOST} ^fortresstraining.com/forum [NC] RewriteRule ^(.*)$ http://www.fortresstraining.com/forum/$1 [L,R=301] RewriteEngine On RewriteRule ^((urllist|sitemap).*\.(xml|txt)(\.gz)?)$ vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 [L] Code (markup): How do I make the htaaccess file stop rewritting the address? I want all urls to point to www regardless of how their typed in.
