We had planned on using Judge.me for our reviews so we can utilize them off our site as well (See https://wordpress.org/plugins/judgeme-product-reviews-woocommerce/). They have a woocommerce plugin that in any theme we’ve tested, including Xstore, it automatically replaces the reviews with theirs, no coding required.
This 3rd party review plugin works perfectly as it should with the default templates your team has created under WooCommerce -> Single Product Page.
We began to test the custom single product builder due to a different issue we were working through (https://www.8theme.com/topic/disable-xstore-lightbox-in-theme-options/#post-373655) and I am thinking the call to get reviews must work differently because the 3rd party plugin no longer replaces the woocommerce ratings in this type of page. I am wondering if the code calls reviews differently on the custom page? Any suggestions is appreciated. Thankyou for your continued help.
