Facebook returns an "undefined" error if the Facebook Page you are trying to load has privacy setting which do not allow us to pull information. The Facebook Page needs to be set to public and have no country or age restrictions for the plugin to display the Page's post. You can easily make these changes inside your Facebook account:
- Visit the settings for the Facebook Page.
- Under general settings, remove any Country Restrictions in the United States, Age Restrictions, or other restrictions that may be blocking access.
- Save your changes.
The Feed should now be able to load. If you still experience trouble, please contact POWr Support.
