File not found

Hi !

My application is working fine with wamp + virtual host
Moving the app online is causing some routing problems.

I've succeed to have a home page working fine but each link gives a simple "File not found." without any styling or precision concerning the file not found.

I've applied indications of this tuto in order to 'clean' my urls :

I've also realized that added routes are case-sensitive in Routes.php

PHP Code:

$routes->add('/', 'pages::view');   // gives a styled 404 error page 


PHP Code:

$routes->add('/', 'Pages::view');    // working fine
$routes->add('(:any)/', 'Pages::view/$1');     // just display "file not found" 


Hope somebody can help me !
Thanks!
