I have been using ipywidgets for quite a while in several notebooks in Databricks, but today things have completely stopped working with the following error;

Uncaught Error: Script error for "@jupyter-widgets/base" http://requirejs.org/docs/errors.html#scripterror

This occurs in notebooks that I have been working with uninterrupted for quite some time, including one where the last change was 69 days ago, so I don't at all understand why this problem would suddenly occur. Any ideas?

(Also I did not understand what is meant by Technical Support - Not for product??)
