I think this may help you, i think that the product designer plugin doesn’t actually change the button. I think that it is hiding the Woocommerce add to cart button, and adding in a button of its own?
So we may have to accept (reluctantly) that we can’t use your plugin with that one 🙁
The products in both these categories use ‘Tshirt Ecommerce’ online designer plugin and therefore should all have a ‘START DESIGN’ button. But when I use your plugin the button is a straight ‘add to cart’ but it should go to the product designer. Your plugin doesn’t even link to the single product page!
I should mention that this plugin renders the product a variable product – but NOT using the woocommerce structure (a pain I know). It uses a completely seperate jquery structure to do it.
