Code below isn't displaying anything. Thoughts on adding an else statement to the if statement at least for debugging so we can see if it is pulling any posts?

Scott Hack comments:

None of the posts have tags. I only want to pull from other posts that are in the custom post type.

do not forget to edit line
$custom_post_type = 'post';

with your post type

Scott Hack comments:

This query doesn't seem to be pulling in any posts, all it is displaying is the </ul> in the code.

Arnav Joy comments:

can you share the full code where you are using my code?

try this

<?php

//try this
wp_reset_query();
$custom_post_type = 'mls';

$args = array ( 'orderby' => 'rand', 'posts_per_page' => '21' ,'post_type' => $custom_post_type );

use following line after the $custom_post_type = 'mls';

remove_all_filters('posts_orderby');
