Flows lost ; where are they gone?

hello
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.)

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?

Hello
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...
