I have been running Node-RED on a RPi 3 for about the past 4 years and just did an upgrade from 0.16.n to the latest and greatest. I used the upgrade script 'update-nodejs-and-nodered' mentioned in the Node-RED doc. Prior to the update I did an image copy of the RPi SD card.
I did see some initial issues after the upgrade, mostly due to the upgraded UI widgets having additional configuration parameters and different defaults. These have been solved through direct examination, reading the various error and warning messages, google searches and just sitting and thinking about some of the behaviours I saw after the upgrade.
The one ongoing problem I am seeing is the dashboard sidebar in the editor is blank. Instead of seeing:
(image borrow from another post)
Instead I am seeing this:
I did check the /var/log/nodered-install.log and did not find and error or warning messages related to the installation/upgrade process.
Likewise, the startup log from node-red-log does not have any warning or error messages:
pi@moode:~/.node-red $ node-red-start
Start Node-RED
Once Node-RED has started, point a browser at http://192.168.10.222:1880
On Pi Node-RED works better with the Firefox or Chrome browser
Use node-red-stop to stop Node-RED
Use node-red-start to start Node-RED again
Use node-red-log to view the recent log output
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot

Starting as a systemd service.

---------------------------------------------------------------------
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.

Without some useful warning and error messages, I don't know where to look or what to google to trouble-shoot this problem.
Any suggestions would be greatly appreciated to solve this issue.
P.S. I am completely new to Discourse so my composition skills are completely new. I how the images I captured and then pasted into this post are visible. Any suggestions with regards to steps, tips and tricks for posting are also greatly appreciated.
