Notices

Please remove the notices from the plugin.

I mean, On line 593 change from if(!function_exists(is_robot)){ to if(!function_exists('is_robot')){

Also on line 118, 122, 126, 127, you have an undefined index, so adding @ in front of $_GET will stop the notices ?? But might want to fix with if(isset($_GET['cache_view_type])){

Thanks
