Page shows up blank?

Hey, I’m using the following code to call my categories. It has been working smoothly so far but today I realized that it’s not working on one of my pages. It loads just fine on the other pages that uses the same code though… Any help would be very much appreciated… Thank you!

<a href="https://celebrityfashiondirectory.com/category/outfitsclothes">View All Outfits</a> <?php wp_list_categories('orderby=name&show_count=1
&use_desc_for_title=0&child_of=19&title_li=<span class="titlez">' . __('Outfit Designers') . '</span>'); ?>

The page: https://celebrityfashiondirectory.com/outfitsclothes-designers
NOT working…

However this one uses the same code /with a different category id) and it loads just fine…

Thanks very much in advance!
