Omega Billing Build 4 Setup

[gandalf4711]

Hello,

I occurred a problem after installing OmegaBill.

I installed it as described in the HowTo... no problems.
I can open it, using address: http://billing.xxx.de
The login screen appears and I can log in using standard user and password (admin, omegabill).

After login, I can see the header, but under the header is nothing ... just blank.

I checked configuration.php settings but I found no error...

any suggestions????

Thanks
OLI
