Change EDITORS rights

Allow editors to edit MENUS:

// get the the role object
$role_object = get_role( 'editor' );

// add $cap capability to this role object
$role_object->add_cap( 'edit_theme_options' );

 

Also, if you want to give access to a certain plugin to the editors, you should edit the mail file of the plugin and replace all strings
