Hi again!
Sorry, but i found a solution for the problem,
i put that code in functions.php:
$role = get_role(‘editor’);
$role->add_cap(‘edit_box’);
$role->add_cap(‘edit_boxes’);
$role->add_cap(‘edit_other_boxes’);
$role->add_cap(‘publish_boxes’);
$role->add_cap(‘read_box’);
$role->add_cap(‘read_private_box’);
$role->add_cap(‘delete_box’);
