Market Commerce product pages not showing or allowing site visitors to add products to cart

We only sell one product currently on our online store, and the page was working fine – but now when you go to the product page nothing shows up and there is no option to add a product to the shopping cart.

We see there are updates to the theme and dashboard plugin. We will update the dashboard plugin, but do not want to lose any “customizations” we have done to the Spirit theme by updating.

Thank you.
