Addthis Buttons Are Disappeared?

Solution 1:

You need to not only call the addthis_widget script every time you load the template, but you need to clear out 'cached' variables.

    if (window.addthis) {
        window.addthis = null;
        window._adr = null;
        window._atc = null;
        window._atd = null;
        window._ate = null;
        window._atr = null;
        window._atw = null;
        }  
    var uniqueUrl = "http://s7.addthis.com/js/300/addthis_widget.js#pubid=XXX";
    $.getScript(uniqueUrl)
    .done(function(script) {
      addthis.init();
    });
