Hi Till, Please help, I have no more idea. I updated Debian 7 to 8 then 9. Apache didn't start so I purged. I've made backup from everything and deleted complete /etc/apache2 directory then reinstall it. Now all services works fine also apache. Default site works, but I can't access ISPConfig Panel. Default 8080 is the port and force https redirection. When I try it the result: 404 Not found. I can access to mumin and phpmyadmin. I tried ispconfig_update.sh script and reconfigure services. Sites enabled: apps.vhost; default; default-ssl; ispconfig.conf; ispconfig.vhost; munin.vhost; So, ISPConfig was installed on Debian 7. Latest update installed. Debian update to 8 then update to 9. Regards
Solved. I purged all php and apache packages, deleted config files and reinstall apache and php. ispconfig_update.sh -> reconfigure services | ispconfig.vhost missed, but restore from backup Now I can access. Resynced all services and all fine. I think the problem was the previously apache and php combo (Debian 7).
