Hello –
I have the Name your Price (NYP), Woothemes plugin and have two products that use the NYP function a Gift Certificate (https://babytalkco.com/beta/give-a-gift/) and an Invoice Payment Page (https://babytalkco.com/beta/make-a-payment/). Whenever a gift certificate is added to the cart, nothing is really added to the cart and no items appear. When an invoice is submitted, the price chosen for the payment reverts to zero once the payment is added to the cart. I opened a ticket with WooThemes support and they narrowed it down to an issue with the woocommerce templates in Classico and said to contact you for support. I did install WooThemes free Storefront theme and once activated the functionality returns. Log in credentials are provided in the private section.
