Google Chrome Error: Uncaught TypeError

[nrml]

The tooltip works fine, it opens, the error doesn't start until I want to close it with 'unfocus' (code for tooltip below). In fact everything to the user seems to be working, it's just that this error gets thrown (show below, it continues to throw the error every time I click afterwards). Any ideas?

JS Code

Uncaught TypeError: Cannot read property 'interfaces' of undefined

It happens only for this particular tooltip:

JS Code

$('.ButtonDeal').each(function(){
		$(this).qtip({
			content: $(this).next('.ButtonDealHtml'),
			position: {
				adjust: { screen: true },
				corner: {
					target: 'topMiddle',
					tooltip: 'bottomMiddle'
				}
			},
			style: {
				'font-size': '12px',
				tip: 'bottomMiddle',
				name: 'dark'
			},
			show: { solo: true },
			hide: { when: { event: 'unfocus' } }
		})
	});
