Remove “Ask a Question about This Product” from X-Cart

At product page, “Ask a question about this product” is displayed, how to remove this sentense, then?

Edit light_responsive/customer/main/product_details.tpl, find:

<div class=”ask-question”>
{include file=”customer/buttons/button.tpl” button_title=$lng.lbl_ask_question_about_product style=”link” href=”javascript: return !popupOpen(xcart_web_dir + ‘/popup_ask.php?productid=`$product.productid`’)”}
</div>

and delete the code.
