Hi,

Currently i'm having one option for payment gateway that are PayPal only. Our shipping cost is free so there is no shipping option. When i'm trying to checkout an order using PayPal or Paypal Sandbox, it not redirect to payment page. It stuck on the last page with an order array.
Before this i can proceed to payment page.
Can you help me to solve the issue.

Hello,

It stuck on the last page with an order array.

Do you mean that you're stuck with the last "debugging" image showing information about products that are in your cart ? If that's the case, your issue is only coming from debugging code which should be removed and which was left through one of your website's file.

Hi Mohamed,

Found what is the issue. Its not from the hikashop. It cause by a custom plugin that shows the cart debugging. I'm trying to get their help to solve the issue.
Thanks.
