Here http://eshop.cmsimple.sk (test/test) I have installed the e-shop. Everything works fine till the last step in the order. Without any warning the order is accepted and I see the summary. But: 1. no email is sent neither to the admin nor the customer - the advanced setting (details to customer) are correct. 2. Reviewing the orders, I want to change e.g. the status or whatever else - I get the Warning "Enter correct value"
Maybe there is some error which is not displayed (low error reporting set in your config or server). Check server requirements for Cart: http://opensolution.org/Quick.Cart/docs/ext_6.6/?id=en-requirements It you can - try different hosting provider or change PHP version. Unfortunately servers can have sometimes strange configuration.
