Seems like the error appears because of setcookie() function in Sessions library, not by Tank_Auth. Because redirect() use header to redirect the page, too, and setcookie() also a header function, so this collision appears. As a replacement, you could render an auto-update page and redirect later. I usually did this:

Code:
function __construct()

{

    parent::__construct();

    if ($this->tank_auth->is_logged_in == FALSE){

        $info['message'] = "You are not logged in. Please login to continue.";  # Message to display to the user.

        $info["url"] = site_url('auth/login');  # The url we gonna redirect to

        # $info['time'] = 2; # Number of seconds the info page should be display before redirect.

        echo $this->load->view('info', $info, TRUE);

        exit;

    } else ....

For the info view in the last echo statement:

Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

&lt;html &gt;

&lt;head&gt;

&lt;meta http-equiv="refresh" content="&lt;?= (isset($time))?$time:'1000' ?&gt;; URL=&lt;?= $url; ?&gt;"&gt;

&lt;title&gt;Information&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

<h3>Information</h3>

<p class='notice'>&lt;?= $message; ?&gt;</p>

&lt;/body&gt;

Please feed back if this method works. Wink
