Sorry if you've read my previous post about category children. I've narrowed down my problem to the fact that my blog can no longer show category hierarchies.
The code I'm using:
<?php wp_list_cats('hierarchical=1'); ?>
I have tried as many variations of it as possible, putting it in different parts of the page, uninstalling plug-ins and even reinstalling WordPress, but to no avail.
Any suggestions would be appreciated. Thanks.
