PNP4Nagios error with Apache

I had a working setup with PNP4Nagios and Nagios. Everything was great.

Friday, I installed NagiosQL.

Since then, PNP4Nagios's web UI doesn't work anymore!

I get this error when trying to access it:

The requested URL /pnp4nagios/ was not found on this server.

Mod_rewrite is enabled, but I guess the above error indicates that it's not working correctly??

The links generated by Nagios (that used to work, before Friday..) look like this:

Here is the relevant output of Apache's error.log:

[Fri Mar 02 15:06:43 2012] [error] [client 172.16.0.139] File does not exist: /usr/local/pnp4nagios/share/

Here is my /etc/apache2/conf.d/pnp4nagios.conf:

Alias /pnp4nagios "/usr/local/pnp4nagios/share"
<Directory "/usr/local/pnp4nagios/share"> AllowOverride None Order allow,deny Allow from all # # Use the same value as defined in nagios.conf # #AuthName "Nagios Access" #AuthType Basic #AuthUserFile /usr/local/nagios/etc/htpasswd.users Require valid-user <IfModule mod_rewrite.c> # Turn on URL rewriting RewriteEngine On Options FollowSymLinks # Installation directory RewriteBase /pnp4nagios/ # Protect application and system files from being viewed RewriteRule ^(application|modules|system) - [F,L] # Allow any files or directories that exist to be displayed directly RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d # Rewrite all other URLs to RewriteRule .* [PT,L] </IfModule>
</Directory>

And my /etc/apache2/sites-available/default:

I'm really lost here.
