I'm sorry to bother you again but, I've tryed the solution mentioned in the post you linked me (catchall and root thing)
$route['*']['root']['/:page/wide-screen'] = array('mycontroller', 'mymethod');
but i keep getting the /error page...
I tryed with autoroute true and false, but nothing changes...
I haven't seen anything in the core code about these routing tecniques (i've downloaded the latest version of doophp , 1.2)
do i have to install a plug in ???
thanks again !
