Search results page redirects to 404 page

Hey,

I am using Vantage on my website http://www.techibiz.com.

Whenever I try to search for anything, I get a Page Not Found error. I search with http://www.techibiz.com/?s=example but I get the 404 Page everytime.

I have tried it after adding some blog posts but it still isn’t working.

Please help..

Thanks,
Akshat
