problems with walkcycle, using BSOD

I started rigging my “alien” using the tutorial of BSOD also now I wanna make the walkcycle work but I CAN’T MOVE THE WHOLE LEG TO THE BACK! Please tell me what’s wrong, here’s the blend file.
I used my own model!
New problem!
When I use the walk cycle and then make it on frame 1 at place 1 and on frame 105 at place 2 and make keyframe it walks from 1 to 2!(YAY!) But at the middle of the cycle it looks like it slides since u don’t move the same speed the whole cycle. Any tips to solve this?

In the Armature tab, turn off Auto IK.

Lol tought I turned it off, thanks alot!
