To test enable search on a server
Go to a site logged on as admin, add search to the site.
A link to admin should appear but it doesn't. It works in 2.8.1 and the latest trunk. I'm not sure why it's not appearing in 2.9. I can't find anyway to make it appear. You can manually get to the admin page by right clicking the reset tool button (to open the tool view), then replacing "?panel=Main" with "/admin/index"
So the admin still exists, and admin can access it, just no link!
