The ikHeelRight, and ikHeelLeft, IK function works as expected. When they are grabbed and moved the knee bends as it should.

The problem is the IK function for ikWristRight, and ikWristLeft, is not working. When moved they do not bend their respective elbows. As far as I can see these IK constraints are in place. ikElbowLineRight, and ikElbowLineLeft, are parented to ikWristRight, and ikWristLeft respectivey, in way similar to how ikKneeLineRight, and ikKneeLineLeft, are parented to ikHeelLeft, and ikHeelRight. Why do the IK constraints for wrist, and elbow, not work?

The problem was caused by using the rig updater from a previous version Blender, and Avastar. The updater does not work well. I had to create a fresh avatar in the current version of Blender, and Avastar.
