hello jodomama, welcome to CI. create a file called temp.php in your controllers dir

then cut and paste this code.

Code:

<?php
class Temp extends Controller {
    function Temp() {parent::Controller(); }
    function index() {echo "hello"; }
}
?>

then browse to http://<HOST>/<CI INSTALL>/index.php/temp/

check config/config.php check base_url is set correctly and index_page is set correctly.. if that does not work then try and follow the trouble shooting section in the guide.
