The pre_get_posts filter is immediately before the loop begins in taxonomy-services.php That is too late. The main query runs long before your template loads. Move your pre_get_posts filter to your theme’s functions.php, or a plugin or MU-Plugin file, and you should see the difference.

If you are trying to use all of the terms in that taxonomy for something, try this: get_terms( “location”, array( “hide_empty” => 0 ) ); You may be trying to return taxonomy terms that have no relationship to any object.
What you want is an index page for custom taxonomies. There is a ticket for that, but it’s not clear what is the most obvious thing to show on this page: 1) a list of all posts attached to any term of that taxonomy, or 2) a list of all terms of this taxonomy? Remember … Read more
I found a snippet of code courtesy of mfields that solved this problem for me, here’s what I ended up using: <?php // Add custom taxonomies to the post class add_filter( ‘post_class’, ‘custom_taxonomy_post_class’, 10, 3 ); if( !function_exists( ‘custom_taxonomy_post_class’ ) ) { function custom_taxonomy_post_class( $classes, $class, $ID ) { $taxonomy = ‘listing-category’; $terms = get_the_terms( … Read more
