Hi -
I have recently received the following warning from Facebook about my site which uses the built-in Facebook authentication plugin (v4.00):

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 BHPC Shop  (AppId: 891206517653436) 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: https://developers.facebook.com/docs/facebook-login/best-practices#buttondesign.


I still don't understand exactly what they are complaining about (colour? shape of the "f"??) but I eventually got round it by replacing the supplied button image (wwwroot/Plugins/ExternalAuth.Facebook/Content/Images/facebook-signing.png) with a new one based on the official Facebook login button.

The developers of ExternalAuth.Facebook may like to be aware of this issue before the FB police hunt down more nopCommerce sites. They aren't the friendliest lot to deal with.

Hi,

did you customized your "Login with Facebook" button ?

No customization: I'm using the Facebook Auth plugin as-is, straight out of the box.

The only explanation they gave was:

We don't mind the text on the button, but we do mind the "f Logo" which is located on the button. It is not in compliance with our Platform Policies

but didn't say what specifically was wrong with the "f".

In case it is useful for anyone else whose site is challenged by Facebook as being 'non-compliant', this is my replacement for the 'facebook-signing.png' file in v4.10:



It's the right size and format for the v4.10 Facebook plugin but doesn't have the shading the original has to emulate a pressed button. The button design is taken direct from the FB Developers site, including the ugly capitalization of 'With'.

To use, just download and replace the supplied /wwwroot/Plugins/ExternalAuth.Facebook/Content/Images/facebook-signing.png

provide the exact link for redirect URL and you will succeed
e.g https://www.example.com/signin-facebook
