Because this is very similar to How to reduce the database query-es I will then give you an outline of a possible solution: You have four similar loops with 1) 1 post && offset=0 2) 4 posts && offset=1 3) 5 posts && offset=1 4) 6 posts && offset=1 so your main query will be … Read more
In order to be able to use template tags, you have to do two things after getting your custom select query: You have to declare the global $post variable. You have to call the setup_postdata($post) function to populate the variables. So, my code had to be changed like so: $results = $wpdb->get_results($wp_query->request, OBJECT); global $post; … Read more
Do not run custom queries in place of the main query on the home page and any type of archive page. This will always cause an issue. If you need to alter the main query, use pre_get_posts to do so. To solve this issue, you need remove your code from your category page and go … Read more

It is most often used to alter only the ‘main query’: add_action(‘pre_get_posts’,’wpse50761_alter_query’); function wpse50761_alter_query($query){ if( $query->is_main_query() ){ //Do something to main query } } (I would also check that is_admin() returns false – though this may be … Read more
query_posts() is overly simplistic and a problematic way to modify the main query of a page by replacing it with new instance of the query. It is inefficient (re-runs SQL queries) and will outright fail in some circumstances (especially often when dealing with posts pagination).
