Hi
Breadcrumbs module is assigned to navhelper position , that means you should add that block into layout file Example to add the breadcrumb module to the default layout open this file /templates/ja_intranet/tpls/default.php and add the navhelper block in this way
<?php $this->loadBlock('header') ?>
<?php $this->loadBlock('mainnav') ?>
<?php $this->loadBlock('mainbody') ?>
<?php $this->loadBlock('spotlight-1') ?>
<?php $this->loadBlock('navhelper') ?>
<?php $this->loadBlock('footer') ?>
Now you have the breadcrumb position available into menu items using default layout
