Upgrade Php 5.4 to 5.6 = 502 error, then blank
Setup is debian jesse, php 5.6, fpm, nginx, maraud 10.1
I thought the issue might be the location of /var/run/php5-fpm/mysocket so I made them all /var/run/mysocket, now no 502 error but just blank pages.
Checked individual site error logs, nginx log, php5-fpm log and nothing. Fpm is running.
Basically I was following this to upgrade wheezy to jesse and it upgraded my php too.
I have a backup, but would like to see if it can be corrected.
Not sure where else to look to see what error is happening.
I'm on Debian Wheezy. Should I upgrade this to Debian Jesse?
Can/should I stay with wheezy and just upgrade php from 5.4 to 7? Do I need to be on Jesse to use php 7?
Can't really find a guide on upgrading from 5.4 to 7 on debian with fpm.
