Breadcrumbs stopped going to third level I'm still learning Drupal, so have a basic understanding, and have been assigned to fix our breadcrumbs.  Apparently it used to go to the 3rd level on this page (https://ccom.unh.edu/theme/auvs), but it no longer does, only to the 2nd level.  It should say Home>Research>AUVs, but it only says Home>Research. 

The Crumbs module wasn't installed.  I've been looking through our modules to try to figure out what is doing the breadcrumbs, but I don't see anything.  If I install the Crumbs module I can't even find instructions on how to implement it.  Can someone give me some guidance here please?  Thanks!
You can search for theme_breadcrumb(), they may develop it with this function ( search in template.php )
