Character entering the ground when he looks down

Hi guys, I have a problem with my character’s movement (I think). Every time I play, I can walk to the normal and up side as well, but when I look at the ground my character simply goes to the floor, I have already compared my character to the FPS Template character, and compared other components as well.
Does anybody know how to solve this???

what does your character blueprint look like. im thinking maybe the way you are rotating is off or maybe a issue with hierarchy.

I used the fps template as a programming example of the MoveForward and Right movements and I also used the same FPS template for mouse X and Y, and in the animation question I followed the documentation tutorial.
