"Storing settings failed" message in MB Services-Events result window

[patrickk64]

Meteobridge 6.3 (May 3 2026, build 4183), FW 1.4
RPi 3 Model B

This is the full message:
"Error: Storing settings failed (/root/meteobridge.conf): backup of /root/meteobridge.conf failed: Read-only file system
Meteobridge settings successfully reloaded"

Is there anything I can do to mitigate this? I'm trying to make some revisions to some events.

Thank you very much.
