Welcome to the forums @Marv

Can you elaborate a little?  
What do you mean by deleting everything?

if you mean, your flows are disappearing, it sounds like you are not **deploy** ing your changes.

Again, can you detail what is happening?  
are you sure it's not related?

As @marcus-j-davies asked, did you press the "Deploy" button after adding a flow?

When making changes - you need to deploy, to "activate" / "lock" your changes in

What is the URL you are using?

it should be `http://{IPAddress-Of-Machine}:1880/ui`

Also check your firewall on the machine that Node RED is running on

`127.0.0.1` is for the local machine (that Node RED is running on)  
But to access it from other devices, you need to use the LAN IP address of the machine.

Looking at that, I can see it's OSX.  
So go to `System Settings` -\> `Network` and you will see an IP address that can be used by others that need to connect.
