EDIT : Everything is now back to normal, Facebook and Netvibes are again working hand in hand without a glitch.
These past few days, some of our users have been experiencing difficulties connecting their Netvibes dashboard with Facebook. These issues include: signing up on Netvibes via Facebook Connect, adding a Facebook widget on a Netvibes dashboard and posting Netvibes links on a Facebook wall.
We are aware of the situation and are working closely with the Facebook teams to find a solution as quickly as possible.
We will of course keep you informed of any progress made towards a resolution of these issues. Thank you for your understanding.
