Unable to Submit Action Type

I have this problem as well.

Any suggestions?

What solved this for me was deleting my Publish action in the Facebook app creation admin, then recreating it, then confirm “Publish to my timeline — Post an article to my Facebook timeline after it is published” is selected in the plugin Social Publisher admin panel, then to try publishing a blog post to my Facebook profile without entering anything in the “Facebook Status on Your Timeline” entry box. Entering anything in that box at this stage was generating error messages and preventing the post from being published, thus preventing the trigger steps to continue.

After this, then the next trigger steps appeared.

No luck…

This is the error I’m receiving:

Failed posting to your Facebook Timeline. Error: {"message":"(#3502) Object at URL https://[my URL] has og:type of 'website'. The property 'article' requires an object of og:type 'article'. ","type":"OAuthException"}
