Syntax error in Node Red object - and node red won't start (hassos)-FIXED

I made a change on a NR object - saved it - when it did not work I rebooted. Now the node red “docker” begins to start - than terminates with these log messages:

' Starting NGinx...

My last backup was 3 weeks ago - I’m hoping that there is some alternative to fixing this other than rolling back. I kind of doubt it - but wanted to ask…

No idea what the error might be, but if you go to the addon configuration page and select to view the unused options, then you can activate safe mode and then try to start Node Red.
Hopefully this will make Node Red start up and you can then correct the error, if you can find it.

I actually think this would have worked Wally. I doubted anyone had a work around and I went ahead and restored the backup. But I tried your procedure out - and I’m 99% sure it would have gave me the ability to reverse the change that I had made (I knew exactly the one that caused the issue). I very much appreciate you taking the time to respond to my question!!..
