Post Attributs missing

Posts are not hierarchical by default so you cannot have a “Parent” for default posts.
Also to enable order for posts you have to do something like this:

add_action( ‘admin_init’, ‘posts_order_wpse_91866’ );

function posts_order_wpse_91866()
{
add_post_type_support( ‘post’, ‘page-attributes’ );
}

This is not a support forum for wordpress. Please address these questions to stackoverflow or wordpress forums.

This plugin doesn’t disable anything on default posts. It only creates custom posts.
