Publicize Not Posting To Facebook

I am having an issue in which I connect my FB account and Twitter account. States connected to both. Write my post. Make sure that both boxes are checked for FB and Twitter. Write my post and publish. It will post to my Twitter account no problem, but it will not post to FB. I have deleted the connection and reconnected multiple times and it still will not post to FB. Any suggestions? I read similar issues and tried the basics but that didn’t work.
