Thank you for your support. My client changed his mind and we no longer need to use the facebook sharing button and so also your plugin.
Thanks,
André
OK!
Maybe I share with you the code I’m using for facebook, it could be that the problem:
<li class=”facebook”>&t=<?php the_title(); ?>” title=”Share this post on facebook” onclick=”window.open(this.href); return false;”>
<i class=”fa fa-facebook”></i>
It’s a custom code I found, the only way to put it and style it the way I needed.
