As I can tell from the screenshot you are using an outdated version of the search. Please upgrade to version 2.4, you can download it from codecanyon.
Steps to safe upgrade:
- Remove all the search instances you have created
- Remove the shortcodes from all of the posts/pages and the widgets as well
- Uninstall the search plugin and delete the files
- Install the new version
This should solve the problem with the statistics page as well.
