If you are running multiple servers with Litespeed it is not uncommon for the new version to show on some before the others. If you are looking to upgrade all as soon as possible and the new version is not showing on that servers Version Manager then you can easily have it show by doing a Graceful Restart via the web admin console. After you perform the Graceful Restart visit the Version Manager located under the Actions menu. You should either see the new version with a download link next to it or the new version with a upgrade link next to it. If the new version is showing a download link wait a couple minutes as that means your server is in process of downloading the new version of Litespeed.
