add_filter( 'learn-press/courses/handle_params_for_query_courses', function ( $filter, $param ) {
global $wp_query;
if ( ! isset( $param['order_by'] ) ) {
$wp_order_by = 'menu_order';
$pattern = '/wp_posts./';
$filter->order_by = preg_replace( $pattern, '', $wp_order_by );
}
return $filter;
}, 10, 2 );
