Once you have created a site, you can only edit certain fields of the site. For example, you cannot edit the site ID and site categories fields once the site has been saved.
Open the Business Control Center.
Select Site Administration.
Select the Manage Site Assets link.
Enter the name of a project and click Continue.
Select a site to edit.
Click the action button and select Edit from the dropdown menu.
Edit the site as necessary.
When a site is edited, the system saves two new additional fields, Last Modified By and Last Modified Date.
Note: If the site category used to create the site has been deleted, and the site configuration has been edited, the site category value for the site configuration will change to the default site category.
