1. Upgrade your theme to the last version.
2. Put this code to the Custom javascript code field. prestashop.on('stUpdatedCart', function(){$('.rightbar_cart .rightbar_tri').trigger('click');});
You have to edit a site file in Panda v1.
Add this code to somewhere in the \modules\blockcart_mod\views\js\ajax-cart.js file accordion to your settings. sidebarRight('products_cart');
I should have been more specific, you need to add that code to somewhere in the “updateLayer” function according to your “Add to cart animation” setting in the “Cart block mod” module.
If you don’t know where to put the code, then let me know the value of your “Add to cart animation” setting.
