Broken link issue

[General Ray]

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.
