Hello,
I have configured JFBConnect with 4 APIs (Facebook, Twitter, Google+, LinkedIn), I've run autotune, I can't see any configuration issues, but only Google+ and Twitter (which shows the word 'Tweet', not an icon) show at the end of Joomla articles.
I cannot see how to make LinkedIn and Facebook show as the configuration seems all the same, and how do I make Twitter show an icon not the word 'Tweet'?
