[done] Loades view as data and a wrong output

More than likely it's this line in PAGES_Loader->create_view():
$this->page['body']['template'] = $this->view($data['template'], $this->page['body']['elements'], '', TRUE);

You have too many arguments for $this->view(), so it's probably starting the output before you get down to $this->view('page', $this->temp);

Bonfire
