LowerLeg is not first child of UpperLeg or Foot is not first child of LowerLeg: you may have problems with Shin rotations.
VRChat's IK system looks at the first child of the hierarchy when determining the bone layout. If you have other child bones, like prop-placement bones, or twist-bones in your rig, they can confuse the IK. To avoid this warning, move the child bone to the first position in the list of children of the parent bone. Note that this message is naming the slot, not the actual bone name in your rig, so you'll have to look to see what bone is in that slot.
