403 no permission while installation

[ghost]

The PHP modules already active.

While Installation - first step - after click on setup he throw me on the index.php and give out a 403 permission error.

I think the problem is the user in the database.
Jo have to set that the user can open also when he not is in the local network

What are the permissions on the files? The Apache user will need access.
