Hi,
Wampserver is primarily designed for novice or beginner users, which is why the syntax of the httpd-vhosts.conf file is checked, and of course, this syntax must remain simple and ordinary.
In this case, you want to change one or more basic VirtualHosts to "professional" and, as the possibilities are virtually unlimited, it's impossible to carry out a check.
In this case, we advise you to put your VirtualHost modifications in a separate file, e.g. httpd-vhosts-sandy.conf, and to add a line at the end of the httpd-vhosts.conf file:
Include httpd-vhosts-sandy.conf
to your file.
