 * I found this error when my php debug enabled, maybe you could take a look.
 * Notice: Use of undefined constant AMPFORWP_DM_SOCIAL_CHECK – assumed ‘AMPFORWP_DM_SOCIAL_CHECK’
   in C:\xampp\htdocs\my-site\wp-content\plugins\accelerated-mobile-pages\templates\
   features.php on line 356
 * This is on localhost, using latest WP, even the error persist after using 2015
   theme (default theme), all plugins disabled except Automattic AMP and you AMP
   plugin.
 * I think there’s no performance affected.
 * Thanks
