You can't just use $categories in the tpl file, you have to assign the categories to the view using the controller

Open

/catalog/controller/module/featured.php

Find this line around line 10

$this->load->model('catalog/product');

Before it put

$this->load->model('catalog/category');
$this->data['categories'] = $this->model_catalog_category->getCategories(0);

And save
