Well this is a different issue.
Now fancybox isn’t there anymore and it doesn’t cause the issue.
So the fancybox related issue is resolved.
I see this in your site using google-chrome console:
Uncaught Error: No layout mode: jquery.isotope.min.js?ver=2.2:12
I don’t know on what it might depend as that js is from the colio plugin which is a premium paid plugin so cannot test it. It might be a theme conflict, another plugin conflict .. whatever.
You should ask to their support in this case.
From the theme point of view another partial issue I see is with the smoothscroll (you can see the page bigger than what it should – this is due to some plugin which sets the <html>
height to 100% and this hurts the smoothscroll feature), you can disable it in
Appearance -> Customize -> Global Settings -> Smooth Scroll or by code with:
add_filter('tc_opt_tc_smoothscroll', '__return_false');
But I don’t think it’s related to your issue though,
Good luck.
