Ok, today, I was playing around with my zend framework.
I noticed that nginx had some updates and I applied them. It stop working after a nice systemctl restart nginx.service.
Now, here's my setup: https://github.com/renich/fedora-configs/tree/nginx
Well, more less. I have things configured for development so nginx has "debug" as log level and php shows all errors; as well as the zendframework setup has "development" instead of "production" as it's env variable.
Anyway, things just stopped working and the bug has been reported: https://bugzilla.redhat.com/show_bug.cgi?id=918351
