Rigify addon error please help

I’m trying to rig a simple model I made but I keep getting this error when I press Generate Rig.

Here’s the .blend file rigged-bunny.blend (3.6 MB)

my guess is the reason why it’s not working is because you’ve deleted some bones that were necessery like feet bones.

ah, yeah that was causing the issue. I used the basic human rig now and it generates but some parts dont move correctly

here’s an updated .blend: http://pasteall.org/blend/index.php?id=52503 (its 1mb too big to upload director to this website =\ )
