Apologies my fault here's both htaccess and routes:

Code:

ROUTES:

$route['default_controller'] = 'home';
$route['404_override'] = '';

/*
| -------------------------------------------------------------------------
| CUSTOM ROUTES
| -------------------------------------------------------------------------
*/

$route['pages/(:any)'] = 'home/pages/$1'; // Pages Routes

$route['login'] = 'auth/login'; // Login
$route['logout'] = 'auth/logout'; // Logout
$route['forgot'] = 'auth/forgot_password'; // Forgot Password

Code:

HTACCESS
