I am happy with using Piwik.
But, I have a like this problem as below case.
when one of my clients ongoing to website via Campaign, for example campaign name is PPPP at 11:30 PM
so i can get log with referral type is Campaign.
and then this client have a conversion after midnight, for example at 12:10 AM next day.
so this Client must get a conversion information with referral type is Campaign, referral name is PPPP.
but this Client get referral type is Direct Entry.
The conversion information of like this case of all of Clients have changed referral type is Direct Entry from the Campaign.
in my configuration file, session time is like this.
visit_standard_length = 86400
Please give me the any comment.
thanks and sorry for my English skill.
