I did a fresh install (files+db) of 2.0 b5 as previous version b2 error log looked incomplete and campaigns weren’t tracking. Now, campaign tracking seems to work, but visitor log is completely empty. Clicking the evolution icon produces this error.
There is an error. Please report the message (Piwik 2.0-b5) and full backtrace in the Piwik forums (please do a Search first as it might have been reported already!).
