Static home page link not working with multidomain

Hi,

I setup a multidomain with this plugin, but when I want to use a static page for my home page, I can’t click on this home page link anymore, because its permalink has my main domain name inside.
The home page is correctly displayed on the homepage, but in the menu the link is incorrect.

Example :
my main domain is http://example.com
My other domain is http://seconddomain.com
On the second domain all pages and link are ok, except the static home page which has this link :
http://example.com/seconddomain/myhomepage.
instead of http://seconddomain.com/myhomepage
