1. go to the pages and find “testing”
2. result box shortcode doesn’t work.
3. even i select search box, the function also not able to search pages content.
The search was not working, because the PHP DOM content parser was failing due to the strange amount of script tags that are visible on the page. It caused a 500 server error, and the ajax request failed.
I have turned off the search for images within the content, now it should be working again: http://i.imgur.com/jiw40uZ.png
