I track several websites through Piwik. I have noticed that the tracking of keywords and referring sites has dropped off since I upgraded from 1.2 -> 1.5.1. I could find no solution to the problem, and thus completely reinstalled 1.5.1 as a fresh install on the assumption that the upgrade process may have missed something. Unfortunately, the new install does not seem to have solved this.
I found a post mentioning a possible missing PHP fopen as a culprit perhaps? Any idea how I could verify this?
All traffic with this problem goes into Direct, except for the traffic that I specifically sent into a Campaign via URL parameters. Even when I specify the keyword for the campaigns via the URL, nothing ever appears within the keywords widget, even though the campaigns properly file. No websites ever show (referrers) either.
Any idea what I can try next?
