First, I turned this line
define('WP_DEBUG', false); in your wp-config.php to the code below to hide warning messages. Warning messages does no harm but is helpful in development mode not in a live site.
ini_set('error_reporting', E_ALL );
define( 'WP_DEBUG_LOG', true );
You're using Pro and there's currently no demo for. Sorry for the wrong choice of words. The demo is not disabled in Pro. X demo is not compatible with Pro due to templating difference. I'm not promising but our development team might create demos for Pro in the future.
Thank you for understanding.
