RigidBody Character Controller Sinking into Floor?

I’ve been using this script: http://wiki.unity3d.com/index.php?title=RigidbodyFPSWalker
Everything works fine, but unfortunately the Controller sinks into the ground slightly and stays there. It would be great if someone could help me (and no, the Character Controller IS over the floor on the y Axis)! Thanks.

Try adjusting the Skin Width of the controller to be bigger, or smaller. Experiment. Also take a look at the Docs.
