I had a weird issue on a PHP script. I was returning an error 404 on a WordPress page the following way :

// At the beginning of a template page
global $wp_query;

  if ( $posts_query-&gt;post_count == 0 ) {
    $wp_query-&gt;set_404();
    status_header(404);
    get_template_part( 404 ); die();
  }

When I was accessing the error page on the browser, It worked well, I had a 404 error page displayed + the correct status code when I inspected the page (Network tab).
