MyBB Community Forums

I have a Home and a Forum page on my forums site that includes a breadcrumb trail. With the first part of the trail, it leads back to to the index page which is actually my home page. I want it to actually lead back to the forum page. Where do I go to fix this?

Looking at the code it looks like (if it's the original file) that it should just link to your board url.

$navbits[0]['url'] = $mybb->settings['bburl']."/index.php";

(global.php line: 506)
