Issues with Rigging in maya 2017

Hello guys, am currently having issues with character rigging in Maya 2017. Anytime i try to bend the rigged character, the foot joints tend to rotate downwards. i didn’t have such issues in Maya 2016. Has anyone experienced such? The screenshots are attached.

Looks like you just need to constrain your feet in some way. If the feet are children of a bone that is bending, they are going to rotate.

You’ve already got your foot control curves in place, so just orient constrain your joints to those and you’ll be in business. Don’t forget to freeze those transforms first.

thanks. would try it now.
