Than you. Assigning the edit_others_posts capability worked.

Thanks for responding so quickly Maria.

My use case is that I have users with a role of either administrator, lms_manager, instructor or instructors_assistant creating, viewing and editing players in the back end. I am not using the contributor role.

Players created by the role instructors_assistant can be seen by the administrator role but not the other way around. ( I changed the id of the author field in wp_fv_player_players to test this.)

It would seem to me that having access to players in the back end based on capability rather than role may be more flexible as the capability can then be assigned to any role.

For now, is there a work around?

FYI: I’m using LifterLMS for creating courses and Advanced Access Manager for managing roles and capabilities.
