Piwik on Mysql 5.7 and php 5.6 shows errors

Support & Bugs
1

Hello,

I get the following message in Piwik 2.16.0-b1.
Running PHP 5.6 and Mysql 5.7

SQLSTATE[HY000]: General error: 2006 MySQL server has gone away - caused by plugin Actions

in most Widgets of the Dashboard.

Unpublishing plugin Actions makes this appear:
SQLSTATE[HY000]: General error: 2006 MySQL server has gone away - caused by plugin Referrers

This happens only. if I choose certain date range. I Updated from php 5.5 to 5.6 and mysql from 5.6 to 5.7 last Month

Also page titles in the widget aren’t shown but only from times before the mysql and php update.

So can I rescue my data? I also ran a new installation of Piwik 2.15 and it doesn’t work normally either.

What should I do?

Kind regards Axel

Please try with our latest Piwik 2.16.0 beta which should fix this issue: I would like to test early beta and RC releases, how do I enable automatic updates to use these development versions? - Analytics Platform - Matomo

Hello,

none of the above or the post helped but this one:
changing default database charset to latin1 and default collation to latin1_general_ci fix the error. .

MySQL > 5.7+ now installs by default a utf8 character set…
…

Kind Regards.
