home controller functions not loading (uri protocol???)

[eluser]fcambounet[/eluser]
I reduced the issue to the ID part of the URL actually not getting through. The function itself, when fired up without any parameter, is recognized.

ie : /controller/function does work
but : /controller/function/id does not work
and the index function is actually called.

This may have to do with the facebook environment / setting under which i'm developping, while using the install guide found here : http://www.simpleprojectz.com/2008/10/fa...deigniter/

I tried changing the uri_protocol to all values though.
