Piwik down since last upgrade - MySQLi error

Support & Bugs
1

Hello,

I upgraded last thursday to the latest version (2.8.0). Since then all the graphs are flat. When looking in the logs, I can see MySQL errors:

PHP Fatal error: Call to undefined method Piwik\Db\Adapter\Mysqli::fetch() in /tank/www/piwik/core/Tracker/Model.php on line 353

How comes?

Thanks

Axel

I have tried a fresh upload of the Piwik source code instead of an upgrade. Same issue, Piwik is down.
Help please.

I have rollbacked my Piwik to 2.7.0 and it works now…

How are you using Piwik, with the Javascript tracker file?

Are you doing anything special with Piwik?

Can you paste the full log line for this error?

Hello,

Yes Javascript tracker.
Nothing special: hosted on Nginx 1.6.1 PHP 5.5.16 MySQL 5.6.19 on Debian latest
Here is the log I have in the nginx error log file:

Is there a way of having a better debug log?
Thanks

Hello Matt,

I have upgraded back to 2.8.0 and applied the patch. No more errors in the logs so as far I know, that seems to be a fix.
I let you know if I come across any problem.

Thanks a lot,

Regards,

Axel

Excellent that’s what i like to hear! it was actually a regression from me that I put in to make the automated tests pass, but unfortunately this created a worse issue. Now it’s fixed and we’ll even simplify Db handling code in the future
