TypeError: $.fn.spin is undefined jquery.spin.js:94
ReferenceError: Backbone is not defined notes-common-v2.js:32
ReferenceError: Backbone is not defined admin-bar-v2.js:2

Sorry. In debug mode it will not access the crop page. Page stay empty… ??

Tried it, same issue.
I’ll try the debug mode.

Thanks for your help.
Everything is up to date. Cleaned cache and cookies, And reset all add-ons.
For me I got the solution/ the problem fixed.
In one of my add-ons there is the ability to load jquery through CDN. Shut this off and voila. Everything is fine now.
