Hi, I have upgraded my dashboard node from version 2.25.0 to version 3.17 and all my UIs no longer work. The buttons for example no longer appear on the dashboard and I can't group them either. Any ideas??
Which versions of nodejs and Node-RED do you have installed ?
Node-RED version: v2.2.2
Node.js version: v15.3.0
Any errors in the browser console?
