I just updated from 2.7 to 2.8, and the only problem I have, is my category list.
It should show the last 5 active categories:
<?php wp_list_categories('orderby=post_date&order=DESC'); ?>
But in 2.8 I get: NO CATEGORIES in my page.
I took a look here: (but I can't find 'orderby=post_date')
So the question is: How can I get a list with all my categories, the ones last added a new post to, on top?
