When using more than share.js plug-in, it may not be the case the application will appear
This is the case where the head of the page is extracted separately, share.js application to reference jquery placed in front of the lead. Because of the extracted individual pages and the current page are quoted jquery, jquery after the references when loading, resulting in share.js lack the necessary code.
Workaround: share.js on the back jquery.js
