My default character stopped moving and can now only jump, any idea what happened and how to fix this?

I opened a new level to follow the complete beginners course on udemy and when I returned to my main level to play around my character was mow only able to jump and that’s it.

Played around some more and found that it was because I changed the name of the inputs from ‘MoveForward’ and ‘MoveRight’ to ‘MoveForwardBack’ and MoveRightLeft’ respectively just to make it easier for a beginner such as myself to understand.
