Hello, Today I have configured successfuly The Perfect Server - Ubuntu 12.10 (nginx, BIND, Dovecot, ISPConfig 3), default ubuntu PHP 5.3.x works with nginx, but when I have compiled my own last stable php version 5.4.13 with this tutorial on page 3 http://www.howtoforge.com/how-to-use-multiple-php-versions-php-fpm-and-fastcgi-with-ispconfig-3-ubuntu-12.10-p3 and added it to ISP Config as another php version, nginx say 502 Bad Gateway nginx/1.1.19. Path in ISP config: There is /opt/php-5.4.13/var/log/php-fpm.log Can you help me to get work with this another php version? And last question I look on nginx and I have very old version 1.1.19 can I replace it with newer? Because ubuntu server apt has this legacy version, so I have added lastest stable nginx repository to my update list, I'm worry about this if ISP config refuse it or something happens... Thank you for help.
