How to make a content type a Ubercart product Basically I want to add the "add to cart" button to a content type.
I've got Ubercart installed and enabled.
Normally whilst editing a content type there should be a section 
"ubercart product settings" where I can check "products... are shippable"

But there's no such section to make it a ubercart product.
Go to admin/store/products/classes.

From there you'll be able to assign a product class to an existing content type, after which you should see the Ubercart-specific settings on the content type edit form.
