As of two days ago, the search feature on my blog has been busted. If I do the search for any word, the URL changes correctly into blogname.com/?s=phrase but index page is displayed. It doesn't display search results. I tried various search terms with same results. I've even tried to run search in FF which I never use and got the same crap.
All I did to the blog lately was upgrade WP Super Cache to c 0.9.9. Otherwise nothing has been done to the blog. Any idea how I could fix it? Help!
