#36 Error "The database is empty for the date of today"

[Jose Augusto Cardoso]

nfsen/nfdump worling fine, I installed but I cant see anything.

The Nfsight showing on settings menu: 'The database is empty for the date of today. Is the back-end script properly configured and running?' and the Nfsen showing on plugins menu: 'No plugins available!'.
I guess that permission to write on db isnt problem, becouse I'm logging by root and I can see the logs there.
