As @colin says `node-red start` will create a new (blank) flow file called `start` - so they would seem to be gone...

I know this is an old thread but I wasted 20 hours until I found a solution to the blank dashboard. You must use lower case for the /ui portion of the URL... ie: [http://127.0.0.1:1880/ui](http://127.0.0.1:1880/ui) Perhaps deep in the code there should be a toLowerCase() so that it will always work.

@dceejay could the fact that the the `ui` portion of the url is case sensitive be classed as a bug? It is certainly most unusual for the domain/folder part of the url to be case sensitive.

No. W3c says the domain is case insensitive (due to dns lookup) but the path can be

Understood. Interestingly (to me anyway), the only part of the fetch that is case sensitive is [socket.io](http://socket.io) which is why, I assume, the page does not show a failure, it just shows a blank page.
