Following this "how to" http://www.howtoforge.com/how-to-upgrade-debian-squeeze-to-wheezy I upgraded squeeze to wheezy; now PHP-FPM no longer works while Fast-CGI does. I have installed ISPConfig 3.0.5.4p3. Thanks for any help.
Please redo all "apt-get install ..." commands from wheezy perfect server guide to ensure that no packages are missing.
