Coursepress JQuery .knob error and others

I had just installed Coursepress for the first time in my theme and it gave me this error:
TypeError: jQuery(...).knob is not a function

I dont know what happend, but turn off and turn on WPMU panel, made this error gone. But another JQuery error now:
JQMIGRATE: Migrate is installed, version 1.4.0
load-sc...ver=4.5 (linha 9)
Error: no such method 'instance' for menu widget instance

...""),isReady:!0,error:function(a){throw new Error(a)},noop:function(){},isFunctio...


It makes impossible to add Courses Description!

Isnt this plugin being updated?
