 * Hello,
    After activating the plugin and going into the plugin settings page, 
   I clicked the checkboxes for “Leverage browser caching” and “Enable compression”,
   hit save settings and get an error saying:
 * “Warning: Cannot modify header information – headers already sent by (output 
   started at /my_server_path/wp-content/plugins/page-speed/function.php:174) in/
   my_server_path/wp-includes/pluggable.php on line 1121”
 * The same error appears even when not checking those boxes and hitting save settings.
   Also, when running the website through the Google Page Speed test, the thumbnail
   image on the google page speed shows a white page with what looks like the error
   mentioned above.
 * Any help with this would be greatly appreciated!
 * **WordPress Version 3.9.1
    Plugin Version 1.1.0
