Apache2.4-style syntax
As Apache has stopped supporting the old syntax, the following should be replaced in all of the Apache2 config files:
handler-apache2.conf: Order deny,allow Deny from all Allow from 127.0.0.0/8 -to- Require ip 127.0.0.0/8
manager-apache2.conf, portal-apache2.conf, test-apache2.conf: Order deny,allow Allow from all -to- Require all granted
and if you wanted to "Deny from all" at any point, use "Require all denied".
