i am getting PHP errors while trying to login while opening auth/index

Code:

A PHP Error was encountered
Severity: Notice
Message: Undefined property: stdClass::$session_name
Filename: libraries/Flexi_auth_lite.php
Line Number: 172

This makes

Code:

$this->auth->tbl_user_account NULL in function ip_login_attempts_exceeded()

thereby giving database error in the end.

Weird thing is checking value in its constructor gives the right value. I have checked this with a new installation of CI and Flexi

what am i doing wrong?
