Thumbnails on Agent page My Listings not showing

[reader51]

I just upgraded from Agent 2.0 to 3.0. Changed some of the code on the agent page php so that only current listings show. Now, none of the thumbnails are showing on My Listings- they do show on the home page and on the category pages. I checked the permissions for cache (755) and timthumb (644). Wondering if the code I added to the agent page might be causing problems.

On page.agent.php, I changed this:

<?php $page = (get_query_var('paged')) ? get_query_var('paged') : 1; query_posts("author=$agent&showposts=5&paged=$page "); while ( have_posts() ) : the_post() ?>

to this:

<?php $page = (get_query_var('paged')) ? get_query_var('paged') : 1; query_posts("author=$agent&showposts=5&paged=$page &cat=-28,-33" . get_theme_mod('blog_cat=')); while ( have_posts() ) : the_post() ?>

website url is: http://66.147.242.185/~michelw6/michelle-maida-2/

any ideas?

thanks.
