How to Reinstall WordPress to Root

1. Log in to your Web host administration panel. This will vary depending on your host, but cPanel is the most common.
2. Open the 'MySQL Databases' configuration page. Highlight your WordPress root database and delete it.

3. Click to create a new database. Use the same database settings as with your initial database. Log out of the administration panel after you are done.
4. Go to the WordPress page on your website to open the installation page. For example, if your WordPress is installed to 'server.com' in the default folder, go to 'www.server.com/wordpress.' Enter your database details in the configuration setup to reinstall WordPress.
