How do I remove link in posts titles

It’s not an expected behavior for the plugin, though I could make the link something more generic. In the meantime, you can manually change the code on your CatListDisplayer.php file, search for this:

    private function get_post_title($single, $tag = null, $css_class = null){
    return '<a href="' . get_permalink($single->ID).'">' . $single->post_title . '</a>';
}

Remove the a tag, and leave just this:return $single->post_title;

This will return just the post title, though this doesn’t give you the link to the post anywhere. Is this what you need?
