URL Canonicalization Issue

Hi guys,

I've got my forum with the vBSEO mod installed... and I've been having some trouble with setting the www. and the non www. in the .htaccess file.

This is the code I'm adding but it's having no effect:

Code:

Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example\.com
RewriteRule ^(.*)$ http://www.example.com/$1 [R=permanent,L]

but I'm guessing this is because of what this mod has put in the .htaccess file

Does anyone have any ideas why it's not working?!

Thanks

Jordan
