Version 1.1 of cPanel WHM works fine regardless of what I read in a previous review below.
I was initially getting an error code 5, and I emailed the developer who responded with the solution immediately. The FAQ at their website also had the answer to my problem which I must have overlooked. Anyways, the fix to the error was to *not* use http:// in the host field. Yippie. It works great.
It will be an even better App once there are more details for each of the features. Kudos to the developer for a good-looking solid app.
