Sometimes, wouldn’t it be nice to uninstall or ‘reset’ your WordPress site?
That’s where WP Uninstaller comes into play. Once activated, you can choose from the following options:
<ul>
<li>delete (or keep) WordPress database tables</li>
<li>delete (or keep) WordPress ‘wp-config.php’ file</li>
<li>delete (or keep) all files and folders in your WordPress directory (yes, that means everything!)</li>
</ul>

WP Uninstaller

Remove WordPress files and database tables with just a couple of clicks!
