get_instance() undefined in custom librairies ? :(

Awww I see... lol.

Well then, I'm simply trying to perform a quick redirection to the default controller when a controller or controller function is not found.

Is there an easy to achieve this ? (I'm using clean URLs)

I've read multiple post where they extend the CI_Route or CI_Extensions with a considerable amount of code.

Is there a kind of "shortcut" for this ?
