Just so you all know, this problem occurs for me when you use the JS code as Google Analytics gives it to you (with the spaces and what not).
If you take the spaces out and plug it in it doesn’t cause this error, but I’m not sure that the code tracks either.
I’ve only had this problem in one of my blogs which I’m not using an analytics plugin for. Other sites that do not have this problem do and donot use an analytics plugin.
This is definitely strange.
