Reply To: custom_post_types don't show up

Thanks for your answer. It’s my own theme.
The mistake was here:
$args = array_merge( $wp_query->query_vars, array( ‘post_type’ => ‘rezepte’ ), $filters );
it was only the array
$args = array_merge((array)$wp_query->query_vars, array( ‘post_type’ => ‘rezepte’ ), $filters );
I didn#t know how to mix the filter from you with the choose of the post type
now it works
