I am having this same problem--Simple Share will not post to Facebook. I get an Unknown Error message. Very strange because I also use another program for flyers called Rezora and have never had an issue posting to Facebook. Twitter also worked fine. I have tried all of the suggested steps to correct. Has a solution to this issue been found? Thanks! @JamesD131 wrote: I have tried sharing campaigns to my twitter and facebook accounts.
