Fancybox does not close


I'm getting an error on my website. When I try to close a frame of Fancybox plugin, it doens't close all. The screen is still locked.

On console debugging I can see this error Object doesn't support property or method 'swing', in this line: this.pos=f.easing[i.animatedProperties[this.prop]](this.state,c,0,1,i.duration)

To see it online, click on some music link on

If someone has idea what should I do to solve my problem, I would thank too much!

There is a problem with your easing plugin. try to get it from here and include
