I can see when I view the source code on those sites that you have:
<script type="text/javascript" src="google_javascript/wagt_maps.js">/*wagt*/</script>
near the bottom.... it is leftover code from having a google map at one point I guess.
You can probably just delete that line and theme it would start working on that page. (probaby a good idea to do anyway).
We'll have to do something to try to prevent client side javascript errors from causing such a big issue.
