From [New version of NR, lost in `settings.js` file - #3 by Trying\_to\_learn](https://discourse.nodered.org/t/new-version-of-nr-lost-in-settings-js-file/55165/3)

That's a tricky point.  
_Same machine_.  
Said machine _died_ and I rebuilt it.  
So it is going back onto the same machine, but a different build of NR (and O/S)

I tried doing what I understand is needed to be done, but it doesn't/didn't work.  
(That was a long time ago)

Well, I hope not. I stopped NR, put the new files in and started NR.  
Lots of scrolling as it started which was kind of normal but some of them were new.  
I didn't screen shot it.  
There couldn't be any hidden tabs as the NR version was too early.
