Here’s an update of how to show empty categories using the default Category widget in WordPress 2.7.  My previous post was for pre-2.7 WordPress sites, this update is still simple; actually it’s easier since WordPress switched to using an array for the category arguments.

In your includes/widget.php file around line 1090, change this line:

$cat_args = array(‘orderby’ => ‘name’, ‘show_count’ => $c, ‘hierarchical’ => $h);

to:

$cat_args = array(‘orderby’ => ‘name’, ‘show_count’ => $c, ‘hierarchical’ => $h, ‘hide_empty’ => ’0′);
