Pages and posts on ElegantTheme featured slider [closed]

There are probably many problems here, starting with the use of query_posts() for a secondary query.

The proper method is new WP_Query(), passing the relevant arguments. For example

$featured_query_args = array(
    'post_type' => array( 'post', 'page' ),
    'orderby' => 'menu_order',
    'order' => 'ASC',
    'posts_per_page' => (int) $featured_num,
    'post__in' => (array) array_map( 'intval', et_get_option( 'aggregate_feat_pages', '', 'page' ) )
);

$featured = new WP_Query( $featured_query_args );

if ( $featured->have_posts() ) : while ( $featured->have_posts() ) : $featured->the_post();

    // Loop markup here

endwhile; endif;
wp_reset_postdata();

Note: this is untested example code, to help you construct a proper secondary query and loop.
