I think, the two issues below might be related.
I have “add to cart redirect” turned off, however AJAX add to cart buttons is active.
I experience the same issues:
– fatal error upon previewing product
– entering shop and then selecting product works; however balance is always shown as zero in the cart preview and as “error: no numerical value” in the checkout.
– what is striking is that when setting top the gift card as new product there are no fields below the amounts.
Using latest versions of WP, WC and your free plugin.
