Pressing "Connect" to Facebook logs me out of my WordPress account

When I press “Connect” to connect to Facebook in the Sharing Settings it logs me out of my WordPress account and asks me to log in with the link below, which – it seems to me- should afterwards redirect me somewhere, but doesn’t. As a result I am not connected to my new Facebook address, and this means I can not publish my WordPress posts to Facebook.
