WordPress MU

Here's an interesting problem. I created a blog separately with Wordpress MU. It was in the "1" position in the blog as the first entry. I had created another blog and imported the entries into the "2" position. Looking at the blog on the back end admin, the categories and subcategories all appear correctly. Looking at taxonomy, etc. they retained their ID numbers (I used phpmyadmin.) so it seems all so far so good. Not exactly.

I had this on a page of the original blogs (using php exec plugin) and it pulls the right subcategories and lists them nicely in the original blog:

<?php
wp_list_categories('child_of=35&show_count=1&hide_empty=0');
?>

However, when I click on that page in the new blog, no subcategories for category 35 show. The database shows that the structures would seem to be identical as are the associations. Can anyone explain why this doesn't work for blog 2?

Oddly enough... I edited one post and now everything seems to have "clicked" into place. I have no explanation for it but this is what happened. Interesting.
