Update: I tried changing
$config['sess_expiration'] = 7200; to
$config['sess_expiration'] = 0;
and
$config['cookie_prefix'] = ''; to
$config['cookie_prefix'] = 'myprefix'; but that didn't help.
All I see on my CI page which has Print_r($_SESSION):
PHP Code:
Array
(
[__ci_last_regenerate] => 1506167810
)
Where as plain.php shows me all the session data.
