Hello,
I am following this tutorial: http://www.codefactorycr.com/login-with-codeigniter-php.html
It works when I copy it exactly as it is. Now, I only wonder why eventhough I try to imitate it and modify it a little bit to match my system, I wonder why it still does not work ?

routes.php
/* admin login*/
$route['admin/login_view'] = 'admin/login';
$route['admin/admin'] = 'admin/home';
/* admin cms */
$route['admin/options_view'] = 'admin/site';
database: indonusaci
table: users
id, username, password
This is what happen: after I login with the correct username and password,
http://localhost/IndonusaCI/index.php/admin/login
Then I start to move to another front page with this url:
http://localhost/IndonusaCI/index.php?verifylogin
I wonder why what appears is different from the tutorial, in the tutorial is directed to home after login, in this case, I would like to be directed to admin page after login which views/admin/admin.php
