CDN not working

Just downloaded and installed. I’m using CDN77 and I’ve integrated it using the tool supplied. The badge sport a CONNECTED string but if you look at my site you’ll notice that the site is not using the CDN.

Just switched from W3 to this one. The CDN under W3 worked perfectly but not here.

Can you help please?
