We are getting this error on demo.piwik.org on an ecommerce website (Marketplace)
A fatal error occurred
The following error just broke Piwik (v3.1.0-rc1):
Key "icon" for array with keys "type, url, pageTitle, pageIdAction, idpageview, serverTimePretty, timeSpentRef, pageId, contentName, contentPiece, contentTarget, contentInteraction, interactionPosition, timestamp" does not exist.
/storage/piwik-demo/www/demo.piwik.org/plugins/Live/templates/getLastVisitsStart.twig line 148
Is there a workaround for this error? I upgraded a dozen installs to 3.1.0 today and just one of them shows this error... Just wondering what triggers it.
We've released 3.1.1-b1 which fixes the issue, please report if you still have the problem (to use the beta channel see: http://piwik.org/faq/how-to-update/faq_159/ )
I've just updated to 3.1.1 and it seems everything it's alright!
