Giving archive.php support for CPT breaks menus

Hello,

I’m using Hueman theme with a child-theme and have added support for CPT to display in archive pages:

• My website: http://www.euroviajar.com/turismo-en-berlin/
• Source of code: http://css-tricks.com/snippets/wordpress/make-archives-php-include-custom-post-types/

But I don’t know why it breaks the menus. Any help would be appreciated.

Thanks,
Kevin.
