404 Error when clicking on bas section of the search result

Hi.
My site is : https://24.37.224.51

When i make a search using the home page search field (ex: Search for the word “VIP”), you will see that the first search result is “VIP en bref”. If i click on the search result, the good page will load only if i push on the search result text or image thumbnails. If i click on a blank space in the search result section, it goes to a 404 error page telling me that the search result is not existing. But if i click directly on the title text or the image thumbnail in the search result, it’s goes to the right web page…

What can i do to repair this ?
Thank a lot.
