fb:app_id correct URL

Hello! I’ve been using your plugin successfully for some time now but now Facebook needs me to provide some information regarding the app I built in order to use the social login feature.

I get stuck at providing the correct url. When I enter website.com/my-account, the Facebook form rejects it providing this information: Missing Properties: The following required properties are missing (from the provided url): fb:app_id

Any help would be appreciated.

Thanks!
