Pre-Order plugin on Product Page Conflicts
It appears that the theme is interfering with the "Pre-Order" plugin on the product page. The Add To Cart label does not read "Pre-order-now" as it should. (see below)
On the Product Listing (/shop) page, it's working correctly. (see below)
We believe this was working prior to your last update.
We also had another issue when trying to use "any" plugin that will allow us to display videos in the product gallery. The videos will only display on the (/product) page if you first load the (/shop) page and then click on the product to go to the product page. Our site is a single-product website, so we're not using the (/shop) page and will just be taking visitors directly to the (/product) page.
