 * Hello,
 * I downloaded the “Hummingbird” plugin to help address some pagespeed issues. 
   I didn’t like what the plugin was doing to my site and uninstalled it. Then performed
   a system restore.
 * I now see this on top of every page of my site:
 * Warning: include_once(/home/everyd18/public_html/wp-content/plugins/hummingbird-
   performance/core/class-utils.php): failed to open stream: No such file or directory
   in /home/everyd18/public_html/wp-content/advanced-cache.php on line 24

 * Hi,
 * It appears that the warning is coming from hummingbird-performance plugin. Please
   can you try to deactivate the plugin? Does the warning message disappear now?
 * Regards,
    Bryle
