Click one of the following, based on the type of hosting you have. You can tell this by the second word in your hosting's description beneath your hosting account's domain name, e.g. Deluxe Web correlates to Web/Classic (Hosting Control Panel).
Your currently-selected version displays. If you want to change it, select a different version, click Continue and then click Update.
Plesk lets you change the ASP.NET settings on a per-domain basis. This means you have to update the settings for each domain on your account if you don't want to use Plesk's default.
