Hi

Installed hotspots yesterday and set up a couple of test hotspots

Map was loading fine on front page of this site

http://www.devsite9.co.uk

It's stopped loading today
Firebug is throwing up these errors

TypeError: category is undefined
south = Math.min(south, category.south);

Error: Permission denied to access property 'toString'

In sandbox.js line 148

Can you help please

Many thanks
