Here are two errors may happen with Facebook integration as a result of the recent Facebook changes. If either of these errors have appeared on your website, here is how you can fix the issue.
Error 01 – App Not Setup
This may be happening because the App ID and Secret in the Metro Publisher Facebook settings are not connecting at all to a Facebook App.
Error 02 – Error Accessing App
This error message happens when the Facebook App ID is correct but the App Secret is incorrect. in your Metro Publisher Facebook settings.
The best way to fix these types of issues is to go to your App page in Facebook:

- Reset the App Secret.
- Check Settings, make sure that there is an Email and that the Site URL is the URL for your Metro Publisher public site.

- Save your changes.
- Return to Metro Publisher admin.
- Re-enter the App ID (to make sure it is the correct one).
- Copy and paste the new App Secret, and **click Enter.
- Save.
