I had to sleep on this.

It suddenly occurs to me that you might be using Node-RED's Project feature?

And you've used "project" as a URL?

So I'm wondering if you have hit a rare edge-case?

Try changing the URL of the "project" instance of uibuilder to something else. to see if that works.

Yes, change the url, click Done and then re-deploy. That last bit is important since it is the re-deploy that actually changes the name.

just remember that after re-deploy, the underlying instance folder will also be renamed. So if you are using an IDE like VS Code to edit front-end code, you will need to change to the new path. The node itself is fine with renaming.

Of course, since you have everything backed up you would not loose anything significant even if you messed it up.

I renamed the url as instructed but the index problem was still there.  
I then updated uibuilder to the latest release V7.3.0 and changed my browser to firefox and now it ALL works!  
Thank you for your time
