No Erros - but no Webfront

[Younex]

Hello!

I hope you can help me.

I installed kolab on debian 3.1 started it without any errors.
All the services are reachabel when i do a ping on them, but when try to
connect to 127.0.0.1/admin,
there is no page(web front)!

The Apache is online and connectabel with 127.0.0.1.
