 * I have this function
 *     ```
       $args = array ( 'cat' => '29,30,31,32', 'orderby' => 'rand', 'posts_per_page' => '1' );
           $the_query = new WP_Query( $args );
           if ( $the_query->have_posts() ) :
               while ( $the_query->have_posts() ) :
                   $the_query->the_post();
                   echo '<a href="'.get_the_permalink().'">'.get_the_post_thumbnail().'</a><br />';
               endwhile;
           endif;
           wp_reset_postdata();
       ```
   
 * It seems running correctly with one record is returned. But somehow, the link
   and the thumbnail returns nothing. If I replace the ‘cat’ with just one value,
   instead of 4 values, it’s working.
 * Am I wrong somewhere? Please suggest.
 * Thanks.
