Can't publish to facebook

[Derwen]

Hi,

When I try to publish to Facebook via Pantheon Photos I'm first asked to log-in with a username and password. After the successful log-in I press the button to publish and I'm told: "You have already logged in and out of Facebook during this Shotwell session. To continue publishing to Facebook, quit and restart Shotwell, then try publishing again." I do as instructed but I'm met with the same message each time. I have and am using the correct Facebook username and password.

I'm using elementary OS 0.3.1 Freya and have Pantheon Photos version 0.1.1+r2806+pkg14~ubuntu0.3.1 (trusty)

Thanks for your help.
