Upfront shows "Upfront_ class not found" live but not in editor?

Hi,

I have upgraded to the latest version of upFront and the new version is a great upgrade in many ways. I have one small problem though and the live web page at http://www.idesystem.com shows an error message in the footer like "Upfront_ class not found", but in the upFront editor there is no object visible to remove?

The error message shows up in both Safari and Chrome. I am using OS X. Support access is granted.

Cheers
