Hi Puszta, did you disable the ZoomEffect on purpose via template settings?
Modal box is part of ZoomEffect and they are meant to work together. Without ZoomEffect the fancybox is not getting triggered.
To trigger the fancybox, follow these steps:
1- open this JS file:
klimaprofik.hu/plugins/system/t3/base-bs3/js/script.js
2- find these lines:
$(document).ready(function(){
//remove conflict of mootools more show/hide function of element
3- replace them with these:
$(document).ready(function(){
//remove conflict of mootools more show/hide function of element
if (typeof $.fn.fancybox !== "undefined") {
var fancyEls = $('.fancybox2, .additionalImagesslider a');
if (fancyEls.length > 0) fancyEls.fancybox();
}
and you should be good to go.
Regards.
