Walk cycle distorts character rig

[EonWilsun]

Please can someone give me a solution or a reason why this is happening.
I rig up my character according to the tutorial I have purchased and tested the movement with the controls and all seems fine but when I activate the walk cycle it distorts my character. Here is the before and after when the walk cycle is attached to the character.
