Facebook WordPress Integration – Publish action

I am using the Official Facebook Plugin to WordPress, and I am configuring the Social Publisher Settings.

Step 2 is:

Associate an Open Graph action-object pair for your application:
people can publish an article

When I open OpenGraph in the Facebook page, there is no “Publish” Action available, so I clicked on the “+” sign and wrote “Publish” and selected “Article” like step 2 says.

And I get this error when I click on “Create”:

A custom Publish action is restricted. Please use the common Publish
action instead.

Where do I find this common Publish action?

How do I resolve this?

Thank you.
