Problems understanding apache config on Mountain lion

Hi

I have installed a site on

/Library/WebServer/Mysite/myfolder

I have configured a virtual host for that in /etc/apache2/extra/httpd-vhost.conf

and have uncommented the vhost directive in /etc/apache2/httpd.conf

However I am unable to get any further than a "Directory index forbidden by Options directive" error in my logs.

As far as I can tell my options directives are correct. They are

Order allow,deny

Allow from all

I have also tried with Options Indexes Multiviews

The permissions on the relevant directory is owner=user and group=_www

I have the server.app installed. and am running 10.8.3 (on a macmini server).

This machine is not accessible from the internet, it is only used locally.

I'm at a loss as to what is causing this? As an info it's a django application thats installed by a professional. But he has not been able to understand why the macmini will not allow me to access the site.

Any and all help would be appreciated.
