Silverstripe 2.2
Apache/2.2.11
PHP/5.2.6-3ubuntu4.2
mysql 5.0.75-0ubuntu10.2
Ubuntu 9.10 - Jaunty

I upgraded Ubuntu last night from 8.10 to 9.04. After the upgrade was complete, silverstripe does not run. the sql server and apache is running. the DB is still intact. when browsing to the site, all i get is a tree of the files in /var/www/ but i cannot get my actual page to show.

Here is .htaccess

### SILVERSTRIPE START ###
RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_URI} !(\.gif)|(\.jpg)|(\.png)|(\.css)|(\.js)|(\.php)$

RewriteCond %{REQUEST_URI} ^(.*)$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* sapphire/main.php?url=%1&%{QUERY_STRING} [L]
### SILVERSTRIPE END ###

anybody else have this problem or any suggestions on fixing it?

Thanks for the reply. I checked all permissions, and they are the same as they were previous to the upgrade. I even went as far as to change everything in /var/www/ to 777 to be sure. I still get just the listing of the files.
