I had a problem where the cookie control plugin wouldn't remember that a user had clicked "I am happy with this" so it kept showing each time you changed pages.
It also wasn't inserting the Google analytics code.
I tracked it down (at least I think this is the problem) to the fact that I had added the function ccADDAnalytics() to the two suggested fields in the setting page exactly as it is written. When the function you should be setting is ccAddAnalytics() with two LOWER CASE "dd" in the name.
I changed this and everything is working perfectly.
Hope that helps.
