I'm trying to update the Server Base URL in Confluence. It was entered as http://localhost:8080/ during install, and I need to change it to an IP address (which will soon be updated to a subdomain). I go to General Configuration > Site Configuration, click on Edit, and in the subsequent form the Server Base URL is grayed out and uneditable. So how/where do I change that? I've tried changing it in the server.xml file, but that just makes it so Confluence won't start.
