Don’t want people knowing which plugins you have installed on your WordPress? Don’t want people knowing what version it is? If you haven’t done this fix yet for WordPress, I can go to http://yourblogurl.com/wp-content/plugins and see everything that you have installed and what version it is.
Not so good for security is it?

If your not code savvy – I’ve made one for you to achieve the same thing and can be downloaded here. (Right-Click and select “Save As”, Upload to your plugins folder, and your done)
