Product not added to minicart

-- HikaShop version -- : 3.0.1
-- Joomla version -- : 3.7.0
-- PHP version -- : 5.6

Hello,

recently I've upgraded to hikashop 3.0.1. In this new version I set the option 'Legacy add to cart off' . However, with this setting off, when I add a new product to the cart, my minicart isn't updated anymore.
My minicart is located as an icon in the toolbar which will popup when you hover over the cart icon. It's configured as a Hikashop cart module.
The add to cart action does add the item to the cart... When you refresh the page or click on another page, the mincart will display the added item. Also the number of item in the cart is visible above the icon.

What can I do to get the mincart immidiate updated when I click on the 'Add to cart' button ?

best regards,

Hello support,

I've solved this problem by myself. I had an override on file product\cart.php. This one did not contain the java part of the 3.0 version of cart.php. I've included that part in my override and it works like a charm!
