List categories wp_list_categories() strange behavior

<?php
   define('WP_USE_THEMES', false);
   require($_SERVER['DOCUMENT_ROOT'].'/w2eat/blog/wp-blog-header.php');
   wp_list_categories( $args );
?>

I use this same code on http://wildreason.com/blog and it works. On http://wildreason.com/w2eat however, it works everywhere aside from the actual blog page http://wildreason.com/w2eat/blog. I am using the same exact code on my root site and it works. I have a list_categories.php with that code located at /w2eat/blog and use an include statement on my sidebar page.

I’ve tried putting the code from list_categories.php directly in my sidebar page and it behaves the same. It definitely wasn’t the upgrade to 3.0 because it didn’t happen to my main site.

Any thoughts?
