The title of this question says it all.

I am trying to update my code from the deprecated _getTracker() method to _createTracker(), but am experiencing inconsistent results.

I have tried traditional and Asynch methods using a JSP include, but they all have the same result. My pageviews, and others in the office all show up in analytics. I have tried various test cases, but their visits are just not registering at all for them, but are showing up for me. The client has tried on multiple machines, and I have walked through with them step by step, so I know it's not just user error.

I know that javascript being turned off will cause the tags not to work, but I am wondering if what else might cause the tags to not be recognized.

I would appreciate any and all ideas.
