Notice: Undefined index: response ......plugins/KeywordTracking/API.php on line 225 (no replies)

Can Someone please help? This error appears only under the Keyword Summary tab in the dashboard and only in one site. The piwik code is already in the body of the site. Clicking the Keyword Tracking tab shows only "ring the request, please try again"

(Piwik 1.12)
