Add to Cart missing on variations product

Hi All,

Using a DXTheme on a dev environment to show clients the power of WP and pluggins available.

However, I’ve got a problem with a product with variations where the “Add to Cart” button is missing.

I have checked and checked and checked and deleted and started again….. with new and old products but cannot get this button to appear via documentation and suggested comments on the net.

Any ideas:

Thanks in advance.

Regards,

Roger
