Answer 1

I found what was wrong. i had

setlocale(LC_ALL, 'tr_TR');

in my /index.php . so weird but session library did not initialize core input . it took me long to find but when i echo

echo var_dump($this->CI);

there was ? (question mark) instead of the char I then it was ?nput . my locale didn't capitalize char i as I , that was the problem. weird thing is it worked in localhost but didn't work on the server.
