I thank you all for you time and patience, I now have a working SABNZBD.
Installed the plugin then reran all the items you suggested but
still getting "Failed to get configuration (xpath=//services/sabnzbd)"
dpkg -l | grep openmediavault - the process sabnzbd is listed
Doesn't appear in the list, its not installed then?
Thanks for that, but i get "unrecognized service" when I "service sabnzbd (or sabnzbdplus) start"
I'm having the exact same problem, and the patch file didnt work for me either (probably my issue, cos, i dont know debian well)
Hopefully a solution comes soon.....
