Cart empties when order createdNO payement option

When my customers attempt to pay via authorize.net but the payment doesn't go through there is no way for them to retry payment? The invoice for the order is created and the cart empties but the payment didn't go through.

That's probably because you're using an old version of HikaShop.

I am running version 1.5.3 and just opened the shop for business. - actually I am just worried because I have a customer that bought something but the order is listed as confirmed. When I ran a test and entered the credit card info wrong on authorize.net it took me back to my shop but didn't notify me of wrong info and emptied my cart. As a customer I assume that I have payed...?

If HikaShop set the order to confirmed, it means that Authorize.net confirmed the payment.
