Enable profiler

[eluser]ninjayan[/eluser]
Hi everyone! So its me again.

I have this code in my controller

Code:

public function __construct() {
  parent::__construct();
  $this->output->enable_profiler(TRUE);
  $this->clear_cache();

  if ($this->session->userdata('is_logged_in') && ($this->session->userdata('is_logged_in') == 1)) {
   redirect('site/dashboard');
  }
}

When I try to login, nothing works but if I remove

Code:

$this->output->enable_profiler(TRUE);

It works fine. How can I fix that? What is the problem?
