Network wide text changes have disappeared after moving wordpress multisite to new domain

Hi,

On the site http://twiddlejobs.com/ no old or new network wide text changes are being displayed either in the frontend or the backend (when i try and add new text changes)

On the original development site: http://twid.simplecsr.com/ the text changes are all clearly displayed and working on the frontend.

Can you please suggest how i can get these back or how to atleast get this working again on the public http://twiddlejobs.com/ site.

Many thanks
Chris
