404... That really shouldn't be

Try changing

Code:

file_exists('application/views/higherone/'.$page.'.php')

to

Code:

file_exists(APPPATH . 'views/higherone/'.$page.'.php')

Also I believe your routes should be, in this order:

Code:

//routes go from most segments to least.
$route['higherone/(:any)'] = 'higherone/view/$1'; //notice () around (:any)
$route['higherone'] = 'higherone/view';
