Hello, I installed ispconfig 3.1.6 on my Ubuntu 17.4 everything is workfine expet the php-fpm, i installed php.5.6 and 7.0 and 7.1 when i try to change the fpm the version is not changing until i restart all php-fpm service "php56.7.7.1 service " so where is the problem ? thanks.
Most likely you have set a wrong init script name for the additional PHP version then. When your service name is 'php56.7.7.1', then use that name as init script name on systems with systemd.
That's not an indication that it's right. Because if it would be right, the ISPConfig would have restarted it already. The only other alternative would be that you restarted it manually with the wrong command so that systemd is not be able to reload or restart it. When your system uses systems, then you have to use the systemctl command to start and stop the service.
