If I use the www.domain.com/subdomain/page address everything works as expected. But if I use the subdomain.domain.com/page address only the first page works. When I click on any menu item the new page is opened but without any styling at all. Both background colour and text size are gone. And if I then try to go to one more page in the menu the link is now subdomain.domain.com/subdomain/page. This still works for standard pages, but also without styling. I have the blog plugin installed, and it does not like this double subdomain at all and only shows Sorry, page not found.
