Thanks for the reply. I am just copying the lsjs folder manually.
But now I am noticing strange behavior. Whenever I load a product page for the first time and try to add the product to a cart, js error "«Uncaught TypeError: Cannot read property 'parentNode' of null»" is showing. If I reload the same page, the product can be added to a cart without any error (i.e Ajax update text is showing).
I've screen capture here in this video link: https://streamable.com/rzmx8p
Can you please suggest where to look for any settings. Thanks
Initially, since there were no products in a cart (mini-cart), cart Html is no present on the page. The script throws an error because it tries to update nonexisting Html. But when reloading, the mini cart is added (as we have added a product to the cart from the previous click action) to the template and hence script works.
Also the check for null at line lsjs.js::87 if ($(el_updated.getProperty('id')) === null) is always false. As $ is somehow jQuery in my installation. This would have worked, as in one of my other installation, if "$" is Mootool.
So to avoid this problem, put miniCart_1 Html on the page and hide it with css class, when there is no product.
