Hi,
In the view "cart / showcarts" in HikaShop > Display > Views try to replace the code displaying the price by:
<?php
$config =& hikashop_config();
if($config->get('price_with_tax')){
echo $this->currencyHelper->format($cart->price_with_tax,$cart->currency);
}
if($config->get('price_with_tax')==2){
echo JText::_('PRICE_BEFORE_TAX');
}
if($config->get('price_with_tax')==2||!$config->get('price_with_tax')){
echo $this->currencyHelper->format($cart->price,$cart->currency);
}
if($config->get('price_with_tax')==2){
echo JText::_('PRICE_AFTER_TAX');
}
?>
