Hi,
my hoster just informed me, that piwik is producing lots of logfile entries like this and asked me if I can fix this:
Tue Oct 21 14:52:54 2014] [warn] [client xxx] mod_fcgid: stderr: PHP Fatal error: Call to undefined method Piwik\Plugins\CoreVisualizations\Visualizations\HtmlTable\AllColumns::getReferrerInformation() in /piwik/core/Plugin/Visualization.php on line 48, referer: https://xxx/piwik/index.php?module=CoreHome&action=index&date=today&period=day&idSite=14 [Tue Oct 21 14:53:00 2014]
please help,
thx,
Robert
