@admin6900, You probably have fixed the issue in the mean time, but the issue resembles a previously posted issue. It had to do with the configuration of Apache’s virtual host.
It needed the following in the virtual host definition:
AllowOverride All
Require all granted
See Browser unable to resolve website and other config issues
@Manu, Since you are not getting a 404 error, I’m not sure if your issue is the same.
