can you provide a link to the LIVE site, please.. I'll take a look at it.
find below the code that relates to the issue
I would like to see it all and determine what else might be contributing to the "issue"
My first thoughts... did you make any of the regions in the dwt editable?
The page at http://www.thesustainableeventsgroup.com/ does not contain any editable regions, there's no ice:editable in the source code of that page as served by your server.
It seems none of the pages from this site contains InContext Editing mark-up.
Have you uploaded the page on the server after you applied InContext Editable Regions?
The site appears to have all the working components needed for ICE atm...
I have a feeling that some people are confusing ICE editable regions with creating an editable region for a dwt...
<!-- InstanceBeginEditable name="MainContent" -->
Good Luck, hope its working now.
