Hi @daledesilva
If you want to check some roles by default in Content Permissions section for posts/pages, you can add this code at the end of your theme’s functions.php file:
add_filter('members_default_post_roles', function($roles, $post_id) {
array_push($roles, 'editor');
return $roles;
}, 10, 2);
and adjust it as you want. In my example I’ve checked Editor role but you can change it or add more roles.
Hopefully, that helps.
