I recently updated from Magento 1.6.1 to Magento 220.127.116.11 and I noticed that the total price of a product changes to 0,00 when I select an option (https://sportinngerritsen.nl/professional-supreme-elite-200-mtr-amber). When I continue to my shopping cart, the price is correct. I've tried a few things I found on the internet like changing a peace of code in the file option
price += parseFloat(this.config[optionId][selectOption.value].priceValue);
Unfortunately this doesn't make a difference. Who can help me with this?
