page shows php instead of html code

Hi to all!

I'm having a problem with codeigniter.

first of all, the website was working fine until I did a little modification on a gallery, but now the page doesn't want to show any pages.

here is the link of the page :

http://www.tuttoturismoweb.com/index.php

I don't understand why is not working. the config files are all ok, everything was working apart the gallery, but now the site is not working any page show always the default code.

someone can help me to understand where is the problem?

Thanks!
