I've got issues with a subsite ... clothncraft.com.au/clothbots
When I do the domain mapping the css doesn't get carried over. I can't keep it up for people to see as the website is currently live and in use.
I've put up a screen dump image here - http://www.clothncraft.com.au/clothbots/files/2012/09/domain-mapping-fail.png
That will show you what it looks like.
Any help would be appreciated.
