Click on checkout sometimes removes cart items. How to debug?
I have a kickstart webshop up and running for little over a week. Orders are being proced normaly most of the time, but two people have complained that when they click the checkout button, the cart-items are deleted.
I've tried the checkout on serveral pc's and platforms and it never happens to me. In this case Google is not my best friend because I've found no report of such behavior.
This issue still could go both ways: computer of client or the webshop. Client computer in one case was a Win7 with IE as well with chrome.
Could anybody give me a hint where to continue the rootcause investigation?
