I've just upgraded Sourcetree and now I'm seeing a Remote icon with a red exclamation mark. When I click it it says "You don't have any remotes which have extended integration settings configured; you need to edit your remotes to add details such as the hosting type and base URL. Click the Settings button to open your remote list."
But when it opens the Remote details dialog and I select Host Type of Bitbucket it automatically sets the Host Root URL to https://www.bitbucket.org. How can I setup a Bitbucket server?
