Hello everyone, here is my problem. Under debian 9, I wanted to change the call port of ISPconfig 3.1.13 and for that I modify the file /etc/apache2/sites-available/ispconfig.vhost I have modified this : Listen 7654 NameVirtualHost *:7654 <VirtualHost _default_:7654> ServerAdmin webmaster@localhost Anf after : service apache2 restart But when i try the adresse xxx.xxx.xxx.xxx:7654 there is nothing and the adress remains desperately on xxx.xxx.xxx.xxx:8080 I would have missed something ?
