Reply To: Enabling Media Library for Authors & Editors

[Vladimir]

I can not reproduce this difference between list and thumbnail views.

I see a mistake in logic. This filter will never return true for user with single ‘editor’ role or user with single ‘author’ role, as 1st definitely can not ‘author’, but 2nd can not ‘editor’.

Try to replace permissions check part with this one:

if (!current_user_can('editor') &&  !current_user_can('author')) {
    return $show_all;
}
