Component in a "Search" doesn't work

[bidierre]

Please have a look at this

http://www.sandalj.com/

The homepage is the very same in

http://new.sandalj.com/

The first works. The second doesn't.

This job is just a remake of the css and a little redesign of the original (ulgy!) website.
Same contents, same structure.
Same plugins uploaded.
Same host.
