Hi,
Looking at your website, you do have the modification I've added in the file media/com_hikashop/js/vote.js but you're missing the other modification I've added in the file components/com_hikashop/views/product/tmpl/listing_div.php
I suppose that you must have overridden that view file in your template and thus you didn't get the change in your override.
Add the code
<?php if($this->params->get('show_vote_product')) { ?>
if(window.hikaVotes)
initVote(newNode);
<?php } ?>
after the code:
var newNode = container.parentNode.insertBefore(div, container);
in the view file "listing_div.php" of the view "product".
