“Listing all metas”

The problem is exactly what the title of this post says. When I add uploader when creating a page, It just says listing all metas forever. So this is what I found when I searched for this in my netbeans:

<?php
/*
 * this is loading all created metas
 */

echo 'listing all metas';
?>

EOF Here.
I checked the network tab in firebug, this does nothing. No ajax calls except the wp-admin calls that are used to check the state of the login. Is this plugin supposed to work on any chance? I have free version. Or is this just a dummy version?
