Armature Pose Angle Garfing Up Pose Mode

I’m following this tutorial: https://www.youtube.com/watch?v=8mZtc33rQ3c

At the 15:30 mark the author describes adjusting the pose angle so all the bones are ‘facing’ the right way which allows you to mirror the left and right sides via copy/paste but my problem is, when I do that step, my model’s feet get all twisted at the shins due to the adjustment of the angles for the feet/sins/thigh/IK’s or something. I can’t figure out how to fix this. What should I do?

I’ve attached my .blender file.

You need to readjust the pole angle on your leg IK constraints. I set them to 90 and that looked pretty close.
