I have 2 flows with a "messed up dashboard", they were just working fine till now.
One Node Red is running locally on a Raspberry Pi, the other is running on a free Ubuntu instance on the Google free tier platform.
Do you mean you have two separate systems that were working, then suddenly they are not working, but you did nothing to them that could have caused it?
Yes indeed, I used several browsers to test including android phone, everywhere this strange behavior.
The node red running on the Google VM Ubuntu instance, I was able to solve the problem by restarting the node red service (systemctl restart node-red).
The node red, running local in my network (used for testing flows before publish them) on a RPI is still producing the scattered dashboard, even after rebooting.
It seems that the complete link to the mgs.payload is displayed instead of the values.
Assuming that you installed node red using the recommended install script, then stop and restart node-red using node-red-stop node-red-start
Note the dashes, it is not node-red start, and copy/paste the full startup log here please, copy/paste, not a screenshot.
After updating, I wasn't even able to connect to the server Node-red server anymore.
This morning, stopping and starting node-red solved the problem (the dashboard looks fine again) and gave me this output:
Start Node-RED
Once Node-RED has started, point a browser at http://10.99.98.11:1880
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.
Started Node-RED graphical event wiring tool.
