To publish your wordpress posts to facebook, there are 2 options.
- Create a facebook app and use the app. (We can use our own app only after getting approval from Facebook)
The facebook app creation and submissions details are available in https://help.xyzscripts.com/docs/social-media-auto-publish/faq/how-can-i-create-facebook-application/
- Use a third party app (It is a paid service)
If you find it difficult to submit the own facebook app for approval, you can use a third party app (which is a paid service starts from USD 10 per year). The details are available in https://help.xyzscripts.com/docs/social-media-auto-publish/faq/how-can-i-use-the-alternate-solution-for-publishing-posts-to-facebook/
You need to select any one option for publishing to Facebook.
If you are using any of these options and still the post is not publishing to facebook, please check the logs section for any error messages and contact support at https://xyzscripts.com/support/ for help.
