i'm still at the basic control - tried a few older versions of codeigniter, all the way back to 1.5, with no results so I am back up to using 1.7.2.

with this set up I am able to successfully browse to:
www.eglisedieuvivant.org
www.eglisedieuvivant.org/index.php

that's it, i got a 404 error for eveything else
