codeigniter and shared ssl

[eluser]Unknown[/eluser]
I am not able to get codeigniter to work on my shared ssl url.
for example, on
https://nimrod.eukhosting.net/~nadavwei/....co.cc/aaa
i get a 404 error
aaa is just a demo controller that should echo test

only the homepage - with no controller in the url - works

btw, i am using .htaccess



thanks
