Looking for some help, all of my sites on my vps are returning a 502 bad gateway. It's ispconfig latest version build on ubuntu 14.04 with php 5.5/nginx/php-fpm following the perfect server tutorial. Everything was working fine up until a day ago. Looked at the php-fpm log and its empty. Listing services shows the php-fpm as not running. When I try to start it it says unknown process. Not sure what to do from here, no one has been anywhere near the server either. Really appreciate some advice.

See if you have any bad php-fpm processing running that is preventing php5-fpm from starting. You will need to do ps ax | grep php-fpm If so kill them off then start php5-fpm sudo service php5-fpm start Second it almost looks like you copy of ispconfig is hosed with all the "No such file or directory" Look for instructions on how to properly reinstall it. Sorry can't be more help than that.
