You may be facing issues when trying to integrate with Facebook. One possible outcome is getting a "This site can't be reached" error.
- If attempting to integrate using the "Connect to Facebook" button, try to use the "Configure Manually" option instead, filling out the FB Name, FB ID, and FB Access Token, as well as the Facebook URL.
- Make sure you are using a Facebook developer account, instead of a personal one.
