I'm getting the following error when I simply "go to" the register/login page

GET http://d2gmp7kf7oi1la.cloudfront.net/media/foundry/4.0/scripts/plupload.min.js net::ERR_NAME_NOT_RESOLVED

l.extend.attr @ easysocial-1.3.28.static.min.js:127
l.access @ easysocial-1.3.28.static.min.js:76
l.access @ easysocial-1.3.28.static.min.js:76
l.fn.extend.attr @ easysocial-1.3.28.static.min.js:126
a.script.a.extend.load @ easysocial-1.3.28.static.min.js:355
(anonymous function) @ easysocial-1.3.28.static.min.js:356

Except, I'm no longer using http://d2gmp7kf7oi1la.cloudfront.net/
I'm now using http://d21tlvg36uvzzq.cloudfront.net/

This happens if I have the cloudfront plugin on or off!

How do I fix this error?
