On the site http://designedwellness.org/products-page/t-shirts/ there are some t-shirts for sale, I'm having an issue with the shipping not working. I have flat rate shipping selected in the store settings, but the t-shirt product pages do not have a shipping meta box. The client is also selling books on the same site, and I was able to set up shipping for that product with no problem. The only difference I can see between the book and the t-shirts is that the shirts have variations.
Right now, the shipping is set to 0. What can I do to get that shipping meta box back?
