403 forbidden for pages with Frames??

Hi All,

Quite new to ISPconfig, just installed my 1st "perfect setup" with http://www.howtoforge.com/perfect_setup_centos5.0

All works well for shared webspace, except pages with frames produce the following error

403 Forbidden
You don't have permission to access / on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

A "flat" htm,html document will load fine, but a page with frames will not.

Here's a bit more with respect to the page config:

Server: Server 1
Hostname: www
Domain: domain.com
IP Address: 192.168.1.50
Create DNS: 0
Create DNS-MX: 0

All files have: Octal 0664

Group X Read X Write Execute
All X Read Write Execute

Any help is greatly appreciated.
