Facebook login button is not showing up

Question

I'm using facebook login on a site to make it easier for users to login or register but I just realised that the login button is not showing up if I'm logged in into facebook. If I log out, it's displayed the expected way.

It used to work before, maybe 2 months earlier but it does not work now.

The fb:login tag is used like this:

<fb:login-button onlogin="myJScript();" />

...

<script type="text/javascript">
 window.fbAsyncInit = function() {
   FB.init({appId: '#{serviceBean.FACEBOOK_API_KEY}', status: true, cookie: true,
            xfbml: true});
  };
  (function() {
    var e = document.createElement('script'); e.async = true;
    e.src = document.location.protocol +
      '//connect.facebook.net/en_US/all.js';
    document.getElementById('fb-root').appendChild(e);
  }());
</script>

So nothing special...

Has something changed in the usage of this fb:login?

Solution

According to the Facebook documentation if you have the show-faces attribute set to true and the user is already logged in, no login button will be shown. Try changing it to false so the login button is shown even if the user is logged in.

You can find more info here: https://developers.facebook.com/docs/reference/plugins/login/

Check your javascript console for any erors. and also see that AppId is present

There aren't any errors and the AppId is present. It works when I logout from facebook. But on my page the same html gets rendered regardless of that of course.

Instead of using facebook login button,you can also go other way around.You can have a normal asp buton with facebook image on it and have the facebook code running on the client click event of this button.This way you can handle the aspx button the way u want.Thats how i did it in my website.

Yes... except if there are no faces to show, in which case the login button does appear! How to work around THAT?
