Title: Added a note on 502 Bad Gateway Errors

Side note on my note. The location of both the PHP-FPM and associated socket file vary from distro and are sysadmin chosen as well. So the assumption is that if they know enough to a) set up Nginx; b) set up PHP-FPM to use UNIX sockets, then they should know where both of those files are on their system.
