Every so often, followers randomly will glitch out and not move. As Kiadony mentioned, using Unrelenting Force to move the follower. Sometimes running into Derkeethus a few times will reactivate him. As for the problem, there's no real way to permanently fix it, that I can tell, just spur-of-the-moment stuff.
