Hi,
You need to edit the file "cart" of the view "checkout" via the menu Display>Views and remove the code:
<th id="hikashop_cart_product_price_title" class="hikashop_cart_product_price_title hikashop_cart_title">
<?php echo JText::_('CART_PRODUCT_UNIT_PRICE'); ?>
</th>
and:
<td data-title="<?php echo JText::_('CART_PRODUCT_UNIT_PRICE'); ?>" class="hikashop_cart_product_price_value">
<?php
$this->row=&$row;
$this->unit=true;
echo $this->loadTemplate();
?>
<?php if(HIKASHOP_RESPONSIVE){ ?><span class="visible-phone"><?php echo JText::_('PER_UNIT'); ?></span><?php } ?>
</td>
and change:
$td .= '<td></td><td></td>';
to:
and:
$td .= '<td class="hidden-phone"></td><td class="hidden-phone"></td>';
to:
$td .= '<td class="hidden-phone"></td>';
