 While following the install guide for Quickr 8.1 HF2 (which is out now, by the way - along with a separate Connectors HF2), the upgrade did not go so hot. After starting HTTP and running the 3 qptool commands, I was only seeing a white screen in the browser - nothing would render in the window.

I did notice when I started HTTP that I received a "- File modified at operating-system level while cached, please retry open." error. So at this point I decided that something definitely wasn't right. I decided to just quit the server and redo the HF2 "installation" (which "is straightforward, basically copying over existing files or adding new directories and files."). This took care of the problem.

The moral of the story: you may wish to completely end the Domino server instead of just HTTP.
