Theme activated but does not display on the website

Hi WordPress gurus,
I hope you can help me.

I have downloaded/installed WordPress in the HOST root dirtectry (it works fine) and downloaded/installed/activated ifeature in the wp-content/themes directory.
When I view my website “www.attivare.com.au”, I get the following instead of the ifeature web theme (untailored):

“Index of /

fantastico_fileslist.txt
fantversion.php
license.txt
readme.html
wp-activate.php
wp-admin/
wp-blog-header.php
wp-comments-post.php
wp-config-sample.php
wp-config.php
wp-content/
wp-cron.php
wp-includes/
wp-links-opml.php
wp-load.php
wp-login.php
wp-mail.php
wp-settings.php
wp-signup.php
wp-trackback.php
xmlrpc.php”

The ifeature theme is nowhere to be seen. I have also tried to install the stock-standard wordpress themes “twenty eleven”and “twenty twelve”. I get the same issue when I try to view my website.

Any ideas/help appreciated

thanks
DJ
