How to prevent European users from purchasing digital goods

If you want to prevent European users from purchasing digital goods, go to the plugin settings dashboard in YITH Plugins -> EU VAT and enable the entry Forbid EU customer checkout. 

In this way, the user can’t complete the order if the cart includes at least a digital product.
