cherokee web server install

[manutitou]

Hi,

On a fresh install of Cherokee with unslung (as per http://unslung.blogspot.com) I have the following problems i can't really understand:
1- When opening in my browser the following http://your-nslu2-ip:8008/phpmyadmin, i get a list being display: Index of /phpmyadmin/
Also when selecting any php files, the browser ask to save the file ?
2- When i try opening http://NSLU_IP:9090 page, and following the login and password entered, i end up with a 500 Internal Server Error...

Any help would ge very welcome

Thanks
