I 've a problem getting the node-red dashboard working.
I did a new installation on ubuntu server 18.04 LTS.
node-red is working fine. I entered and configured a "switch"-node and a "text-input"-node. Configured the dashboard settings and deployed the config.
When I open or refresh the page http:localhost:1880/ui, ther is only a white screen showing: "Welcome to the Node-ReD Dashboard" Please add.......
I restarted my node-red and looked at the node-red-log (see beneath)
Can't see what is going wrong,
Can anybody help me get this thing going.
NOTE: I'm not a Linux specialist (just a beginner ;-), so please guide me with clear instructions.
Thanks in advance

Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.
You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

Already solved the problem myself.
Problem was in de nodejs version. I used the latest v13.11.0 which is not supported yet.
After removing this version and installing v10.19.0 my UI is working fine.
After that I also tried v12.16.1, which also works fine
Maybe this will be helpfull for any other beginner like me
Well done for getting there before someone suggested that
A good way to install (or update) node-red on Ubuntu is to use the recommended setup script which works for Raspbian and Ubuntu and other Debian based systems. That would have ensured you had a compatible nodejs version. https://nodered.org/docs/getting-started/raspberrypi
