I use BSS Magento 2 Pre Order version 1.0.9 for my site Magento 2.2.3 (theme MGS). However, I found that when we add simple product from the category page, there is no product added to cart.

Please guide us how to fix this issue!


The js error appears due to the fact that on M2.2.3, there is no file app/code/Bss/PreOrder/view/frontend/templates/listing.phtml.

To resolve this issue, please download the attached file below and overwrite the current file on your site.
