First, thanks for the prompt reply.

1) Already tried and still the problem
2) It is very difficult to prove. But before works and not now.

The method I use to install the buttons is:
shortcode and pasting the snipet

Something I forgot to mention is that locally works well and does not work online.

Examples:
online version
https://drive.google.com/file/d/0B8NJxS6VgfioQ04xX2MtaW9mcVk/view?pli=1

Local version

I can also show modifications made to apply the plugin to content
