Snapshot doesn't save to dropbox

Snapshot works fine, it creates the backup locally, but nothing is uploaded to dropbox, and no information is shown in the logs.

The app “WPMU DEV Snapshot” is authorized in dropbox, and the “/Apps/WPMU DEV Snapshot” folder is created, but always empty (although I see it in spanish as “/Aplicaciones/WPMU DEV Snapshot”:wink:

What should I do now?
