Keyword not defined (no replies)

I have recently upgraded ot the most recent version of lovely Piwik and am getting a "keyword not defined" for current tracking.

I have read that there is an issue with Google not passing the keyword through, but I am logging my sites with a unique instance of BBClone as well as Piwik. BBClone records all keywords [fortunately!] but not Piwik for some strange reason.

Should I have set something in Piwik's settings since updating, perhaps?

Many thanks for reading this!
