Hello!

The error seems to be coming from your scripts.js. What are these scripts for, and where are they from?

Edit:
More specifically, this function is causing the error

// Function to ping servers
$(function(){
	
		$('.pingUp').attr('data-count',c)
		.countTo({
		    from: 0,
		    to: c
		});
});

What servers are you pinging, and what for?
