Piwik 1.12: keine Besucher-Graphen mehr und Fehlermeldung von archive.php


#1

Seit dem Update auf piwik 1.12 werden im Dashboard in der Besucherübersicht zwar noch die Zahlen ausgegeben, aber keine Graphen mehr.
Das selbe bei Besucher -> Übersicht.

Außerdem läuft der periodische Aufruf von archive.php ebenfalls auf einen Fehler (scheint der selbe zu sein)

Im error.log des Webservers steht:

There is an error. Please report the message (Piwik 1.12) and full backtrace in the Piwik forums (please do a Search first as it might have been reported already!).

Warning:
Invalid argument supplied for foreach() in /srv/www/vhosts/piwik.myhost/piwik/core/DataTable/Renderer/Console.php on line 157
