Reply To: Empty array when ordering posts by meta_value

The issue for me was specific to $query->set('s', ' ');. I added it to fix empty search queries returning a 404 page.

I set a bunch of other query vars in the same function but going through one by one, this was the only one to cause error.

Btw, you’re missing a single quote before date_published.

  
function property_filters($query) {

  // ...

  /**
   * Fixes issue with blank search queries returning 404
   */
  if (!is_admin() && isset($query->query_vars['s']) && empty($query->query_vars['s'])) {
    $query->set('s', ' ');
  }
}
add_action('pre_get_posts', 'property_filters');
