I solve it by replace lines 75 to 78 of q2w3-fixed-widget.min.js by this code :

var infinite_reload = jQuery('body').hasClass('infinite-scroll');

jQuery(window).on('scroll.' + options.sidebar, function (event) {
	var scroll = jQuery(this).scrollTop();
	if ( !infinite_reload && ( scroll + widget.fixed_margin_bottom >= trigger_bottom )) { // fixed bottom

Have fun !
