Facebook Login Button does not appear in Logon modules

Hello,

I am using the Musicity Template and Joomla 2.5.9 on my recent released website.
Unfortunately I cannot see the Facebook Login button anymore on any of my user logons, despite having template settings and plugin settings for the FB login set.
I have already consulted the wiki article http://www.gavick.com/documentation/joomla-templates/templates-for-joomla-1-6/how-to-implement-the-login-with-facebook-feature/ once again but I could not solved it.

You can see this issue on my website within the modules called "Dein Football Flight Profil" und as well at the top button "Login": http://footballflight.de/

Any advice is highly recommended.

Thank you in advance,
Erik
