i got the following message from Facebook:
In working to create a great Platform experience for everyone, we ask developers to ensure the apps they build comply with our Platform Policies. Your app webwinkelforum WWC (AppId: 411298116363531) doesn’t comply with the following:
Platform Policy 8.3: Use a clearly branded “Login with Facebook” button and follow the Facebook Brand Guidelines: https://www.facebookbrand.com/.
Your Login button doesn’t properly reference Facebook. To fix this issue, you should always use our official SDK for Login. For more information on Login best practices, check out the Login section of our developer documents: Best Practices - Facebook Login - Documentation - Facebook for Developers.
You can access the full list of our Platform Policies here: Platform Policy - Facebook for Developers.
