Hi Bruno,

Can you send us the IP address of the CDN server you are getting the default.include-footer.87dfde.js file from. You can see this on the Net tab in Firefox or, even better, you could just send us a screenshot of the Net tab in firebug where a request for default.include-footer.87dfde.js file is visible when this error happens.

Thanks for your help.
Better help the Dev Team instead of posting the same question over and over again.
