Hi Igor,
Thanks for reaching out to us. Unfortunately, we have no such script which is related to the cart.
Could you record me reproducing your issue using a tool like this? https://www.useloom.com
It helps me to quickly figure out the issue.
Thank You
Cart randomly clears
Igor Maly
While using Variation Swatches, the cart empties by itself at random: when switching to another product page, when reordering items on shop/archive page, when adding something to cart, when using filtering by category… Deactivating the plugin stops these random clears, so I guess it’s this plugin causing it.
