Search button doesn't work.

Reported by Xavier:

The autocomplete drop-down work well (we can click on suggestions and are redirected), however the search button doesn't work (can't click).

This appears to be related to a problem with your theme.inc file: this file which is (I think) supposed to override the search form block isn't working well. The drop-down appears, but we can't get to have other modifications done through the theme.inc work. It seems the theme override isn't complete.
