Broken link issue
 

Simple question referring to the page tree. At the top of every page, above the navbar, the tree that lists {site name} > {Template} >{forum}... that one? The link to the main php index (the one I listed as {site name}), is a broken link. The problem is, I'm not used to the phrasing Vb uses in their templates to fix it. Plain and simple, how do I fix the link?

Thanks.

Check the URL set in "Site / URL Options" in vBulletin Options.

Everything is all good in there. It's a 404 error btw.
<if condition="$show['breadcrumb']">
<span class="navbar">&gt; <a href="$nav_url">$nav_title</a></span>
<else />
$nav_title
</if>
Is what it appears to be listed under.

And where is $nav_url defined? That isn't a standard vbulletin variable.

That all came from navbar_link in the navbar and bread crumbs template.
EDIT:I got it, thanks anyway. Here was the problem:
Should have been:
