Multistore with 2 different domains

[japanknife]

Hello

 

I have Prestashop 1.5.3.1 and I want to have two shops with two different domains, for example:

 

 

www.books.com

www.music.com

 

 

I'm trying to do this by following these instructions

 

 

http://www.loading.es/blog/2012/10/16/configurar-sistema-multitienda-en-prestashop-1-5-x/

 

 

But it doesn't work.

 

I speak with my hosting and they said that I don't need to change anything in my server and if it doesn't work is because it is a prestashop problem.

 

Sorry for my English.

 

Thanks in advance.
