I’ve upgraded Piwik from 1.1 to 1.2.1.
After these campaign goals doesn’t track anymore.
Some research let me wonder that the _ref cookie was not created.
So I think Piwik can’t know the landing page URL/ campaign at a later time and so the matching goal <-> campaign couldn’t work.
Does anybody know why the cookie will not be created?
The fix-referrer-attribution patch (#2168) doesn’t fix this.
