Fatal error: Call to a member function elapsed_time()

[eluser]monkster[/eluser]
Hi all,

I'm getting the below message:

Code:

hello world!
Fatal error: Call to a member function elapsed_time() on a non-object in /Applications/MAMP/htdocs/Album4me/components/com_comprofiler/plugin/user/plug_Album4me/codeigniter/system/libraries/Output.php on line 164

And this is my controller file's contents:
class Album4me extends Controller {

Code:

class Album4me extends Controller {

    /*function Album4me()
    {
        parent::Controller();
    }*/
    
    function index()
    {
        //$this->load->view('hihi');
        echo "hello world!";
    }
    
    function _output($output)
    {
        echo $output;
    }
}

Any ideas please?
