Hi,
To customize the order either edit the publish date to make those reflect the desired order or make use of the theme’s roseta_boxes_query_args
filter to customize the query that retrieves the boxes content.
$args = apply_filters( 'roseta_boxes_query_args', array(
'showposts' => $options['theme_lpboxcount' . $sid],
'cat' => cryout_localize_cat( $cat ),
'ignore_sticky_posts' => 1,
'lang' => cryout_localize_code()
), $options['theme_lpboxcat' . $sid], $sid );
$custom_query->query( $args );
