I found the same problem the shopping cart doesnt show correct (it shows nothing) when it does i cant continue after verifying the purchase.

Hello Roman and Pera,

may I ask you to better explain the problems you have with the ecommerce? If the problem is with th epreview you can try to open it keeping the CTRL key of your keyboard pressed.

If you still have problem you can tell me your url so I can verify the issue, thank you
