Show all wordpress categories with no posts
If you would like to show all of the categories on a wordpress site even if they have no posts, here’s what to do…
There’s an argument called hide_empty which is true by default.
File Location is: wp-includes/category-template.php
Look of this code and change from true to false
$args = array(‘hide_empty’ => FALSE);
Also look for ‘hide_empty’ =>1 and change to ‘hide_empty’ =>0
