Autoposting fails

Hi, it seems auto posting is failing on all 3, Facebook, twitter and LinkedIn. I manually posted to Facebook, it said it went but did not show up on facebook and the buttons do not change color as normal when it has been posted.
Can you advise if something is wrong,i recently had a similar problem with the last website i installed EB on, not sure if it is something i am doing or the version. I have used it on multiple sites before without any problem.

Kindest, Leah
