I've found a bug at Visit.php, line 608: detectRefererCampaign() relies on currentUrlParse, but it is only called when $this->refererUrlParse['host'] is not empty. this is not good ;-)
Regards, Christian Menen Keywords: campaign
Can you please describe what action leads to the error? How the error looks like? Error Messages? Unexpected Behavior?
thanks for reporting, fixed on svn see
