Flows lost ; where are they gone?

I was working with nodered for some month, and suddenly, my flows have disappeared.
It seems that one node or one flow makes node-red crash.
I can see it when i run node-red manually.
Ok, I can understand this, even if I didn't make no chnage in the involved node
But what is strange is that my flows have disappeared.
In my flows, there are some notofications wich are sent by IFTTT and a mail, also.
I receive the notification and the mail. so that means that my flows are still in may machine
but when I try to access to the node-red interface, by starting node-red with the comman --safe mode, to be sure that no flow is started, it works
But unfirtunately, I can see no more flow in the :1880 web interface.
How can it be?
Where are my flows?
How can I get them back on the node-red web interface?
I use :slight_smile:

The chances are that your machine has changed its name, which is used in the flows filename or you are starting Node-RED as a different user.

Change directory into your .node-red directory and see if there are more than one flows files in there. ( the startup messages list the directory you need and what the current loaded flows file is called.)


Quiet strange

How can the name of my device change?

How can i know the name of my device,
and modify it?

It's a PLC, running a kind of debian

Show us the whole of the startup log. In there will be the name of the flow file in use.

Also have you done this?

finally, I found the error.
My flows have not diappeared
I made an error i the safe mode commande
In the help, it is written to type node-red --safe mode
But in fact, it is just necessary to type the command node-red --safe
I don't know the complete mecanism of node-red, but with the command node-red --safe mode, it tries to lauch a flow called mode, wich doesn't exist on my machine...
And so, I see an empty flow...
