My blog, located at http://www.hinghamweather.com/bostontvnews, is having a search issue. The search function is no longer working, and gives a 404 error when something is typed in it. action=”/index.php” right now, should it be something different?
Since you are self-hosted and using the software downloaded from wordpress.ORG, you need to direct your question to http://wordpress.ORG/support/ . This forum is for users of WordPress.COM, the free hosting service, and it uses a modified multi-user version of the software which is different from what you are using and few, if any, here know anything about it.
