I recently did the installation of ISPConfig 3.1, using nginx and debian 8 in VPS Vultr. Is very nice! Reading some other outdated topics, I saw possibilibilidade in earlier versions of ispconfig to set up old versions. 1- https://www.howtoforge.com/how-to-build-php-5.6-fpm-fastcgi… ezy 2 - https://www.howtoforge.com/how-to-use-multiple-php-versions… eezy Many people answered the topics and could not run in said setting up. https://www.howtoforge.com/communit...st&o=date&g=1&c[node]=23 25 27 35 34 29 31 33 Someone there is did this test? Could indicate the path where to start? For instance, running version 5.3 and 5.6 php.
