Hi,
You 'must' have controller for home page, it is defined in config/routes.php
Most probably you have:
function index() {} in that controller, meaning:
domain.com/yourdefaultcontroller.php/index will work as well :-)
By the way, why don't you switch from domain.com/en simply to domain.com/fr (with redirect or such)?
Cheers,
Smilie
