Uncaught TypeError: window.Modernizr.prefixed is not a function

Hi,
I am getting the above error on my site (WP 4.3.1).
http://www.garbolino.fr/preprod/

This issue prevents the display of my plugin master slider, and my responsive menu… I think that created as a javascript conflict

It happens at line 1005 in site.js:

// normalize vendor prefixes

var doc = document.documentElement;

var transform_prop = window.Modernizr.prefixed(‘transform’),
transition_prop = window.Modernizr.prefixed(‘transition’),
transition_end = (function() {
var props = {
‘WebkitTransition’ : ‘webkitTransitionEnd’,
‘MozTransition’ : ‘transitionend’,
‘OTransition’ : ‘oTransitionEnd otransitionend’,
‘msTransition’ : ‘MSTransitionEnd’,
‘transition’ : ‘transitionend’
};
return props.hasOwnProperty(transition_prop) ? props[transition_prop] : false;
})();

Any help for the issue is highly appreciated!

Thanks for your reply.
I will try it, but 1 week ago, everything worked. I did not install new plugin.

Hi Alin, thanks for the reply,
In fact I’d like to update the theme, but do you think this could change the entire layout of my pages?
Thanks.

I tried to update my theme… It’s a disaster…
Everything has change… I can’t let this new theme. It give me too much time to put in place the same options and layouts than the previous version.
I will try to disable the plugin one by one to find the issue

However, I no longer have the issue with Javascript and Modernizr (with the theme update)
