codeigniter 3.1.9 session failure

that methods seems not to work either, the thing is when i var dump my session right innthe requestpage controller i am able to get the results but cant be accessed in the other controllers.




thats my response when i var dump the following,

var_dump($_SESSION['customer_data1']);
var_dump($_SESSION['customer_data2']);
die();
