Fix error: only one usage of each socket address (protocol/network address/port) is normally permitted: ah00072 in XAMPP (from http://stackoverflow.com/questions/18300377/xampp-apache-error-apache-shutdown-unexpectedly)
#The issue appears to have been Apache conflicting with itself due to there
#being two Listen 443 directives, the one I added and one via include:
<IfModule ssl_module>
#Include conf/extra/httpd-ssl.conf
Include conf/extra/httpd-sni.conf
SSLRandomSeed startup builtin
SSLRandomSeed connect builtin
</IfModule>
#In the conf/extra/httpd-ssl.conf appears the conflicting line:
Listen 443 https
#Dropping the Listen 443 I added resolved the issue.
#Comment the line and it fixes
