#1 Empta page after installation

[hansi200]

I installed the application corresponding to the howto
on Fedora C4. To make sure for testing purposes, all
users including "Others" have rwx access to all files
and folders. Running the link creation script through
the browser created link files. But when I want to
access the application I only see a complete empty page
(client as well admin). Do you have an idea of what
might be the problem?
