I have updated Quickbox to version 2.3.6 from the dashboard.When I click "Deluge" in packages, the "System Response" pop up will appear, but it won't show any information. It just stay there forever and nothing happens.
We just settled a patch for this and it was due to the hashing involved with the users password. You can run the update from your dashboard and this will pull in the updates.
You can see the patch here:
