How does one suppress a 404 status code in a WordPress page?

1. You can either add custom rewrites to your pages. Or on the top of the template files that wrap your other pages just output header('HTTP/1.1 200 OK');.

2. WordPress offers the function status_header() to return the correct status-code.

   You can call this function inside your WordPress template/function:

   // Will return http status header "200 OK"
   status_header(200);

3. WordPress is PHP, so look for where it’s sending something like:

   header("HTTP/1.0 404 Not Found");

4. Take a look at the pre_handle_404 hook (added in v4.5.0):
   https://developer.wordpress.org/reference/hooks/pre_handle_404/

   // add to your functions.php
   add_filter('pre_handle_404', function($preempt, $wp_query) {
       global $wp;
       $customPages = ['custom-1','custom-2','custom-3'];
   
       if (in_array($wp->request, $customPages)) {
         $preempt = true;
       }
   
       return $preempt;
   }, 10, 2);
