Hi,
I got the same problem!
When I type u-spirit.heliohost.org/cpanel, I'm redirected to http://stevie.heliohost.org:2082/frontend/x3/index.php...
I can't add my domain (addon domain) and got the same error message ("Error from domain wrapper: Bind reloading on stevie using rndc zone: (...)").
Please, help.
