My archive query contains a custom posts_per_page, order, orderby, post_type and paged (via wp-pageNavi).
array ( 'order' => 'DESC', 'orderby' => 'title', 'paged' => 1, 'post_type' => Array ( 'post', 'cust_article', ), 'posts_per_page' => 15, );
My post_type contains 'post' and 'cust_article'.
I have 1 'post' and 65 'cust_article'. posts_per_page is currently set to 5 in admin.
My problem is that the maximum amount of pages is limited by the amount of pages 'post' contains. Since I have only one 'post' the pages are limited to 1, even though I get all pages displayed (5 pages, posts_per_page set to 15), pages other than page 1 will return 404.
Creating a second 'post' and setting the posts_per_page to 1 allows access to the second page, following pages will also return 404.
I'm using the same query for my custom post_type archives, with a single post_type, adding a second to the query creates the same error.
I know that the paging is limited by the amount of posts and the set option posts_per_page. 5 ppp and 21 posts => maximum of 5 pages
By theory posts from 2 post_types should extend the post count. 5ppp and 21 posts + 12 posts => max 7 pages
