The solution was to edit my /includes/loop-search.php file in my child-theme.
there i have added this line in the (single post) footer area:
<footer class=”entry-footer serachattachments”>
<?php
echo wpba_attachment_list( array(‘post_id’ => get_the_ID() ,’show_icon’ => true, ‘no_attachments_msg’ => ”) );
?>
</footer>
