We have not tested the theme Weaver II PRO. It’s a paid version.
But we have developed a child theme of Weaver II that adds the necessary templates for eCommerce.
Joy, a community user has sent an improved version that we could send you.
About PRO version, could you ask Weaver about support for pro theme before buy it?
Weaver a few months ago told us that childs for Weaver II PRO theme must have certain peculiarities. We asked for it to take them into account but we have not been answered yet.
Let us know and count on us to work on compatibility with Weaver II PRO.
