Hello members, Following multiple php (php-fpm & phpfastcgi) with ispconfig tutorial, I have compiled php-5.5.38 as php-fpm on ububtu 16 running with ispconfig 3.0.x . log /opt/php-5.5.38/var/log/php-fpm.log shows that it is loaded successfully fpm is running, pid 13606 ready to handle connection . But the web instance only calling the default php7 . I have also compile phpfcgi but no luck. Already configure the php-fpm & fastcgi at additional php section at ISPConfig and available at client section. Please advice how to make the compiled php work with ISPConfig.
