A great plugin with great support. Very quick to address any issues that arise, which are rare.
Excelente, pone marcas de agua a los plugins que se descargan desde woocommerce.
La opción de que tengan una contraseña personalizada está solo en la versión pro
Wonderful Resource!
It works perfectly.
I experienced a Critcal Error when trying to dowload our PDF that was due to the tmp functions being blocked by our server host. Caroline at WaterWoo Technical Support was extremely helpful and fast in diognosing this issue.
This is a great plugin.
