[Plugin: WP Smiley Switcher] Broken PLugin

Install WP-Grins for Jquery and your emoticons will dissapear. It’s ver probable that with WP-Grins (normal version) will do the same.

If you want to uninstall this plugin and get the comment form the way is was back then, you only can delete the files. And this won’t help a thing.
