Hello there,
yesterday i noticed a problem with the cart.
When i add a product to the cart the modal popup is showing up and i can select the "show cart" button but card remains empty.
If i select the "continue shopping" Button cart is updated. Now i can click on the cart (right top corner) and products are showing in card correctly.
For a temporary solution i've disabled the modal popup in vm configuration. So users are directly forwarded to the cart.
Im using Joomla 3.6.4, Virtuemart 3.0.18 am PHP 7.0.13
