When these two values are the same, then your orderby statement does not tell how they should be ordered. In the SQL world, order is not an inherent property of a set of data. Thus, you get no guarantees from your RDBMS that your data will come back in a certain order — or even … Read more
Third party themes are off topic, but I ended up checking it anyway: The Problem What comes before & after your posted code is important: Before: // Return array of cached results if they exist. $featured_ids = get_transient( ‘featured_content_ids’ ); if ( ! empty( $featured_ids ) ) { return array_map( ‘absint’, (array) $featured_ids ); } … Read more
pre_get_posts is not a filter hook, it is an action. Also you should not set orderby to menu_order for posts as they are not hierarchical. Set orderby to date instead. function modify_query_amount_shown( $query ) { if ( $query->is_category ) { $query->set( ‘posts_per_page’, 30 ); $query->set( ‘orderby’, ‘date’ ); } } add_action( ‘pre_get_posts’, ‘modify_query_amount_shown’ ); Now … Read more

This is taken from an example in the WP_Query() Codex entry: <?php function wpse54142_filter_pre_get_posts( $query ) { if ( is_feed() ) … Read more
Try: $postslist = get_posts( ‘orderby=ID&numberposts=15′ ); Here, we’re ordering by the ID, which should relate to when the posts were added to the database.

next_post_link and previous_post_link order not working properly
Why does pre_get_posts() return “date” as the orderby parameter for every sortable column?
Order char by post title
I think in this case it is probably easiest to create your own function or two. I’m giving you a rough outline on how to do it below. // use the same filter to get the same results add_filter( ‘posts_fields’, ‘wpcf_create_temp_column’ ); add_filter( ‘posts_orderby’, ‘wpcf_sort_by_temp_column’ ); // perform query $q = new WP_Query( [ ‘post_type’ … Read more
