Shared button of facebook

Hi, I haved installed this plugin, it works great, but I found a little issue, and it is that when the pdf is generated the “Share” button of facebook is not displayed, I had displayed a link instead.

What I am doing wrong?.

And other question, can I select some items not to be displayed in the pdf.

Thanks for your great work.
