I am using the latest version of your Pro plugin, and of Divi: 3.0.100

As you mentioned, I went to Settings > User Role Editor, and turned off “Force custom post types to use their own capabilities”.

This fixed the error.

However, I really need that option. Unless you could supply a method to implement it via a function.

I really only need that option for one of the roles, and for one post type.

I have a custom role that, when logged in to wp-admin, only has capability to:

  1. read
  2. create_polls
  3. publish_polls
  4. read_private_polls
  5. delete_polls
  6. edit_polls
  7. delete_private_polls
  8. delete_published_polls
  9. edit_private_polls
  10. edit_published_polls
