Uncaught TypeError: $(...).superfish is not a function

I am getting this javascript error readiong: Uncaught TypeError: $(…).superfish is not a function

I never touched any of that, so I don’t know why I am getting that error message. I provided screenshots. Can anyone help me fix the Javascript errors I am getting? My website is: https://roadfurylifts.com/

Any help is greatly appreciated!
