I've installed Protect Content and I'm interested into the post by post protection (including some of my custom post types posts).
That's why I activated the "Post by Post Protection" as well as the "Custom Post Type Protection - Post by Post".
But I've encountered 2 issues.
1. I've some notices on the "Protected Content" page, in the "Custom Post Types" tab. View screenshot attached.
2. I don't have the "Membership Access" metabox in my custom post types posts edition page. Only in the regular post edition page.
