I still don't have a clue how to fix it...
I've installed the newest version of OMV on muy Pi 3... I don't know how to remove that annoying error. I don't even know where I could find the cli/cmd. I ran the command "nano /etc/openmediavault/config.xml" over tasks then set it as a daily task and manually run it immediatly. Didnt have any sense because it gave me another error.
Who can help me with this problem because I can't solve it myself neither Google helped me...
Thanks
