Thank you for the awesome software. So glad I found it.
There is an error in this page:
I think there needs to be either a backend or currenthost set for the backup to work.
This:
curl -b "skin=desktop" -d '[{"action": "metabackup"}]' -H "Content-Type: application/json" -X POST http://your.rompr.installation/backends/sql/userRatings.php
Becomes:
curl -b "skin=desktop;currenthost=Default;player_backend=mopidy" -d '[{"action": "metabackup"}]' -H "Content-Type: application/json" -X POST http://your.rompr.installation/backends/sql/userRatings.php
Also, I couldn't find a way to access the metadata backup panel shown in the docs.
Thanks,
Trent
