You don't have permission to access / on this server. (1 reply)

Hello,
new install of wampserver 3.1.9 64bit. After installing all those VC++ packages, running flawlessly.
Added a new virtual server according to documentation - also worked.
Only if i call the virtualhost via [newhost], I get the error message:

Forbidden
You don't have permission to access / on this server.
Apache/2.4.39 (Win64) PHP/7.2.18 Server at newname Port 80

hm...
thx for help!
