Codeigniter无法在移动设备中加载所请求的文件

I am getting a Unable to load the requested file: default.php error in codeigniter whenever i load up the website in a mobile device. It loads perfectly in desktop browser.

here is how my controller is set up,

class Welcome extends CI_Controller {

    public function index()
    {
        $this->template->set_layout('default')->build('welcome_en');
    }

}

Default is Sparks template i am using for the current template i am using for the "welcome_en" view page.

I have been trying to figure out this problem for a while now, there is no user agent detection script being used, there was before but i took it out in hopes of getting rid of the error.

You may need to create web and mobile folder. More info

Instead of application/views/layouts/default.php try application/views/web/layouts/default.php and application/views/mobile/layouts/default.php.

Same for all your other layout files, they will load the mobile version if you browse to the page with anything CodeIgniter thinks is a mobile phone (not an iPad).
