 * Hostgator in responding to issues over Heartbeat suggested I add the following–
 * add_action( ‘init’, ‘kill_heartbeat’, 1 );
    function kill_heartbeat() { global
   $pagenow; wp_deregister_script(‘heartbeat’); } A good bit of controvery is where
   to add this. I dug through more the coding, and I found the answer is two places.
   One being the functions.php file of the current theme, and one being within the
   wp-includes/plugin.php file. This ensures it always is working, regardless of
   what is called. The functions.php file of the them “might” be good enough. But
   I found it sometimes is not. The plugin.php is something always called, so that
   is a safe bet to run it. Since you cannot call a deregister function twice, you
   will probably want to place it somewhere that is called quite often. The theme’s
   functions.php is called 90% of the time on the site, as is the plugin.php of 
   the wp-includes folder. My go-to (as it were) is the theme’s functions.php, but
   if that doesn’t work for you (or the theme doesn’t have one), then the wp-includes/
   plugin.php should work just fine.

 * Never de-register core WordPress scripts! I think your hosts gave you some pretty
   bad advice and you need to go back to them about this.
