I wrote about Piwik and OWA here - http://forum.piwik.org/read.php?2,73759,73784#msg-73784
I was originally going to add this on the end of that, but actually I think it is rather important to check, so I thought I would post it separately.
P.P.S I also do wonder whether the Piwik code isn’t in some way interfering with the way Clickbank counts referers? (Clickbank.com)
Can this be checked?
The days I had the Piwik code on nine sites pages I made no sales, from those sites, which is VERY unusual.
I took the code off to try out OWA (and put the OWA code on the pages) and within two hours had 2 sales.
It did make me wonder about whether the Piwik code could mess up Clickbank Tracking in any way?
