Is Cladeaintranet a dir name or your controller?
1. if it is a controller then CI look for a function called index(). How about you adding a simple function i.e
function index(){
echo 'it works';
}

2. Also if it is a directory then what are you calling on that Url?

3. Or assume you called it by route then that name needs also point to what controller and function
