To delete your WordPress installation and start all over with a new/empty WordPress site:
(This assumed you used the control panel to install WordPress initially)
– In your control panel (control.appliedi.net), go into the ‘Application Packs‘ area under your domain, click the WordPress link, and click the option to uninstall.
– then, go to the ‘Database Manager‘ area of your domain, and delete the MySQL database that your WordPress site was using.
You can then go back to the ‘Application Packs’ area and re-install WordPress.
