Yeah. Ok…so I found the issue is seemingly with Facebook.
Facebook is having a serious problem with itâ€™s API.
Today â€œImage postsâ€ to Facebook are stopped working. You can get â€œOK Your post has been sentâ€ status but post wonâ€™t appear anywhere on facebook.
It is not an autoposter problem, it is a Facebookâ€™s internal problem with itâ€™s API. Problem will resolve itself once Facebook fix it.
