 * functions.php
    function my_home_category( $query ) { if ( $query->is_home() &&
   $query->is_main_query() ) { $query->set( ‘cat’, ‘1’ ); } } add_action( ‘pre_get_posts’,‘
   my_home_category’ );
 * I’m trying to set up to appear more than one category entretando still fails.
   
   I tried: $ query-> set (‘cat’, ‘1, 2 ‘); or $ query-> set (‘cat’, array (‘1 ‘,‘
   2’)));
 * but it still fails
