$root_url not working?

[mjwalsh]

It seems as if on a lot of the links the $root_url is not working or updating.. and on my xml sitemaps it's not updating the $website variable properly to match my config. It displays as http://loftyporn.comvideo/ instead of adding the / after .com... this is also happening with a lot of links where it's not using the $root_url to make the link http://loftyporn.com/whatever instead of what it's doing now which is just adding the folders ont op of whatever link you're at now which doesn't work with SEF urls.
