 * Hello guys,
 * I’m a user of W3TC plugin and happy with outcome made by the plugin. Recently,
   I tried to optimize one of my site and message appeared at my admin dashboard
   once the plugin activated.
 * This is what the error:
 * Warning: Attempt to modify property of non-object in ….lib/admin/notify.php on
   line 30
 * Warning: Cannot modify header information – headers already sent by (output started
   at …../wp-includes/option.php on line 748)
 * Anyone ever experience such error? If yes then I hope you don’t mind to share
   the solution to me.
 * Thanks in advance.
