The query works when i remove:’category__and’ => array( 20, 61, 74, 28 ), but i need to get the posts that ar assigned to different categories.

The code is fine i think becaus when i change the query to: * ``` $args = array( 'post_type' => 'product', 'posts_per_page' => 10, 'orderby' => 'date' ); ``` * I left out the ‘categorie_and’ and it works. So i think it is the query that is not wright? But i can’t seem to figure out what is wrong. * Moderator [keesiemeijer](https://wordpress.org/support/users/keesiemeijer/) * (@keesiemeijer) * [13 years ago](https://wordpress.org/support/topic/wp-query-3/#post-3835269) * Very strange.

Try it with a tax query: * ``` $args = array( 'post_type' => 'product', 'posts_per_page' => 10, 'orderby' => 'date', 'tax_query' => array( array( 'taxonomy' => 'category', 'field' => 'id', 'terms' => array( 20, 61, 74, 28 ), 'operator' => 'AND' ) ) ); $loop = new WP_Query( $args ); ``` * [http://codex.wordpress.org/Function_Reference/WP_Query#Taxonomy_Parameters](http://codex.wordpress.org/Function_Reference/WP_Query#Taxonomy_Parameters) * Moderator [keesiemeijer](https://wordpress.org/support/users/keesiemeijer/) * (@keesiemeijer) * [12 years, 12 months ago](https://wordpress.org/support/topic/wp-query-3/#post-3835278) * > Maybe this will help? * Yes it does. The query doesn’t include your category query by looking at the ‘ request’ and no posts were found. * I think a plugin or theme is filtering the query. What plugin are you using for the product posts?
