Hi guys,

I'm new to Codeigniter. Im trying to access the tank auth register page but I get this error msg:

Fatal error: Class 'Model' not found in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\codeigniter\application\models\tank_auth\users.php on line 13

I did follow the instructions provided here:

Can anyone please help me out?


Thanks
