Orderby not working

Theres a bug in the archive page. particularly the orderby option . It should be ‘orderby’ not ‘order_by’

$available_accomodations_args = array(
'post_type' => 'eshb_accomodation',
'paged' => $paged,
'post_status' => 'publish',
'posts_per_page' => $posts_per_page,
'orderby' => $posts_order_by, // <-- fixed 'order' => $posts_order
);
