First page link doesn't work

Hi all, i’ve made this site at this link: http://www.museobianconerocesena.it . This link is a redirection to the really hosting site where wordpress is installed: http://www.museobianconerocesena.simply-webspace.it . The problem is that if I’m in the hosting site i can use the first page links (if i click on facebook or youtube links i can automatically be directed to facebook or youtube site for example), but if i’m in the redirection domain (www.museobianconerocesena.it) these link doesn’t work, if i click on them they doesn’t bring me to their sites.
Why this behavior??
Please someone that have an idea how to solve this problem.
