I have used yith-woocommerce-wishlist with woocommerce, and Post Grid (premium) work very well, but when I use yith-woocommerce-wishlist-premium, it doesn't work. I am sure that wishlist have been activate, and it match with version of php, wordpress and woocommerce, but Post Grid still ask me to activate it. How can I deal with this problem? It is important and urgent for me.
Thank you very much.
