Several things.
Check your configuration.php file and look for the variable live_site? Do you see it there? What does it have?
There is a cross domain javascript problem.
Long story short.
You call your site without www.
But the ajax requests are called with www. and the browser things that something is wrong and doesn't allow it.
On the other hand if you call the page trough:
www.californiaclassics.co.uk/index.php/reel-locations
then the requests are exectured, but there is a javascript error:
ProgressbarControl is not defined
progressBar = new ProgressbarControl(map, { ....
So what have you changed in the settings?
About the map not found message - find the marker that generates it and change it location (although this sounds somehow strange - with version 1.0 you should be able to show the markers even if the google geocoder doesn't know the location).
