Yes, we have the same issue at 4.3.4
Please add fbAsyncInit function in the first statement in public.js to load the FB event when FB is initiated.
window.fbAsyncInit=function() {
if ($(".efbl_feed_wraper .efbl_custom_likebox")[0] || $(".widget_easy_facebook_page_plugin .efbl-like-box")[0] ){
FB.Event.subscribe('xfbml.render', function(response) {
var animclasses = $('.efbl-like-box .fb-page').data('animclass');
$('.efbl-loader').remove();
$('.efbl-like-box iframe').addClass('animated ' + animclasses);
});
}
}
This works fine.
