Problems with php5-fpm/nginx/ownCloud after upgrade

[Peter Ludikovsky]

Hello,

Recently, I upgraded my home server from Wheezy to Jessie. Ever since my
PHP web stack doesn't work anymore, mostly affecting the ownCloud
installation. The problem manifests itself as an empty page served.

Software/Versions:
* ownCloud 8.1.1, installed from their Debian repo
* nginx 1.6.2-5
* php5(-fpm) 5.6.9+dfsg-0+deb8u1
* postgresql 9.4+165

So far I've attempted to enable FPM logging, but the log files remain
suspiciously absent or empty. nginx doesn't see an error coming back. If
I run ownClouds index.php on the command line I get the source for the
login page just fine. Listening in on the FPM port I see that only an
empty response is returned.

I have attached the scrubbed configuration files for nginx and php5-fpm.

Any help is much appreciated.

Regards,
Peter Ludikovsky
