Remove 'home' link from breadcrumb

This can be done by setting the homeLink property to false, in your CBreadcrumbs widget initialization. This is usually done in a layout file.

In the default Yii app, in protected/views/layouts/main.php:

<?php if(isset($this->breadcrumbs)):?>
    <?php $this->widget('zii.widgets.CBreadcrumbs', array(
        'links'=>$this->breadcrumbs,
        'homeLink'=>false // add this line
    )); ?><!-- breadcrumbs -->
<?php endif?>
