Session gives me Disallowed Key Characters.

[eluser]Unknown[/eluser]
I have a very annoying problem.

I use session and standrard seem CI create a session at page loading. It looks like this:

Code:

array(4) { ["session_id"]=> string(32) "adbec1756192db5c29dcc5ad9dc541ed" ["ip_address"]=> string(9) "127.0.0.1" ["user_agent"]=> string(117) "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_1) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/14.0.835.202 Safari/535.1" ["last_activity"]=> int(1318836159) }

When I reload the page, I get the error: Disallowed Key Characters.

How can I solve this?

My controller:

Code:

class Start extends CI_Controller {

    public function __construct() {
        parent::__construct();
        $this->config->load('custom_config');
    }
    public function index()
    {        
         var_dump($this->session->all_userdata());
    }
}

I save my session configuration in a separate config file as I install my application and can not have it in the config.php from scratch

Code:

$config["sess_cookie_name"]     = "lotus-session";
$config["sess_expiration"]      = 7200;
$config["sess_expire_on_close"] = FALSE;
$config["sess_encrypt_cookie"] = TRUE;
$config["sess_use_database"] = TRUE;
$config["sess_table_name"]      = "sessions";
$config["sess_match_ip"] = FALSE;
$config["sess_match_useragent"] = TRUE;
$config["sess_time_to_update"] = 300;
