On a WooCommerce site I manage, with the “Load comments with Ajax.” option enabled, WooCommerce products display a “Comments are disabled” message instead of the product’s (existing) reviews.
This site uses discourse for commenting on posts and pages, but NOT for products (i.e. it uses native wordpress for comments / reviews on products).
I’m sorry, but we have had to revert this commit. It was causing issues with the Remove WordPress Comments Template option. We can look into other ways of preventing issues with the Load comments with Ajax option soon. It should be possible to do that without breaking other functionality.
