Pagination 404 Not Found child page

Question

I have a page Heemtijdinghen displaying custom posts (post_type=artikel) paginated. The page is a child page of page Publicaties: /publicaties/heemtijdinghen/

When navigating to e.g. page 2 a 404 Not Found is thrown: /publicaties/heemtijdinghen/page/2/ => 404 Not Found

However, pagination does work correctly when I make the child page a parent page: /heemtijdinghen/page/2/ => OK

I have no clue how to do the rewrite:

add_filter('init', 'plugin_name_add_rewrite_rules');

function plugin_name_add_rewrite_rules() {
  add_rewrite_rule('publicaties/heemtijdinghen/(.?.+?)(/[0-9]+)?/?$', 'index.php?post_type=artikel', 'top');
  add_rewrite_rule('publicaties/heemtijdinghen/([^/]+)(/[0-9]+)?/?$', 'index.php?post_type=artikel&paged=$matches[1]', 'top');
}

Help would be very much appreciated.

Answer 1

does your query have this

$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array(
  'posts_per_page' => 3,
  'paged' => $paged
);

query_posts($args); 

see documentation about pagination http://codex.wordpress.org/Pagination
