I set, System > Checkout > "After a product is added to the cart", to "Stay and display a popup notice". Therefore, after I click the "Add to cart" button, HikaShop correctly opens a popup window so I could choose either, "Continue Shopping" or "Proceed to checkout."
If I then choose "Proceed to checkout" it correctly closes the popup window and goes to the checkout screen. However, if I choose "Continue Shopping," nothing happens. The popup window remains open and does not return to the store.
In System > Checkout > "Continue shopping button's URL", it is set to
www.m2820.com/index.php/store
Is there something else I'm suppose to setup so the popup window will close?
