Piwik.php broken after 2.14.0 upgrade; always returns 400

Support & Bugs
1

Since upgrading to 2.14, all tracking has stopped on my five-site setup. piwik.php is returning 400 with a useless payload, and the call results in no tracking.

Any incoming request, e.g.:

curl ‘http://{hostname}/piwik/piwik.php?action_name={page title}&idsite=2&rec=1&r=782288&h=8&m=44&s=25&url={escaped page URL}&_id=b98288daaf7749cd&_idts=1428762921&_idvc=5&_idn=0&_refts=0&_viewts=1436543065&send_image=0&cookie=1&res=750x1334’

yields this response:

HTTP/1.0 400 123
Piwik is a free/libre web analytics that lets you keep control of your data.

I haven’t the time to sort out a rollback right now, but I’ve forced piwik to serve up 404s until I have time to do so, in case there is background damage happening.

Hi there,

Can you enable tracker debug logging: Tracking HTTP API: API Reference - Matomo Analytics (formerly Piwik Analytics) - Developer Docs - v3
and then load this piwik.php page and see what it says?

The problem is the location_browser_lang column being missing from piwik_log_visit. (Before you ask, the database user running Piwik has all privileges.)

I’ve seen other people with this issue on other threads, so I’ll go see how to resolve it. Why an upgrade would break things so hellishly is beyond me, though.

Found the workaround:

http://forum.piwik.org/read.php?2,127838,page=1#msg-127877

Only the location_browser_lang column was missing for me.

ALTER TABLE stat_log_visit ADD COLUMN location_browser_lang VARCHAR(20) NOT NULL;
