 * Hello SG Optimizer team,
 * I love your plugin and had been using for years but today unfortunately I faced
   an issue with your plugin that detects an error after activating your plugin;
 * Warning: Cannot modify header information – headers already sent by
    /var/www/
   wp-content/plugins/sg-cachepress/class-sg-cachepress-supercacher.php:104) in /
   var/www/wp-admin/includes/misc.php on line 1116
 * Warning: fsockopen(): unable to connect (Connection refused) in /var/www/wp-content/
   plugins/sg-cachepress/class-sg-cachepress-supercacher.php on line 104
 * Warning: Cannot modify header information – headers already sent by (output started
   at /var/www/wp-content/plugins/sg-cachepress/class-sg-cachepress-supercacher.

 * Hi Dorji,
 * I think there’s another plugin messing with the headers. If you’re using the 
   latest plugin version, I would recommend that you post a ticket in your help 
   desk so our support team can look into it further.
