Blank page after ubuntu update

Postby atrus » 20 Sep 2014, 23:35

Looking for any pointers or suggestions. Running TTRSS 1.13 on a VPS (linode), and it's been running just fine. nginx for web server, postgres for db.

Ran an ubuntu update, including the packages below (*). Now I'm getting a blank page when trying to open ttrss. Nginx doesn't report an error, just an http 200 response going to the client. Postrgres doesn't show any errors.

I've verified that I can still connect to the database (ie, taking a backup of the ttrss db). I've verified that other pages/apps served up by nginx are still working correctly. The TTRSS updater still appears to be working right.

Any thoughts? Would there be any kind of ttrss-specific verbose/debug mode that might give some more clues?

(*) list of packages updated:
libjpeg-turbo8-dev:i386
base-files:i386
znc-dev:i386

Well that was quick. Some googling pointed at the following change to my nginx config:

- include fastcgi_params;
+ include fastcgi.conf;

The only difference between those files appears to be:

+fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

I'm far enough away from php that I don't really have a clue what that means, but everything seems to be working again. Anybody that feels like educating me, feel free :)

Leaving this up just in case anybody else runs into something similar I suppose -- definitely not ttrss-specific though, so feel free to close/delete this as off-topic if you want.

It's just setting a PHP global variable. Read more here http://php.net/manual/en/reserved.variables.server.php if you're curious.
