This is not working for me. It needs another key for work, where I was directed to create a subdomain under .oneall.com web site. I entered my web site but it told that the sub domain already exists. Funny thing is that I went there for the first time. Anyway, I could not activate it for me.
I try this at the moment too. I thing it writes on every try all data into the OneAll database and checks then if a failure will happend. If something wrong it tells you that and then when you correct it (mostly duplicate thanks this bug) it will crying about a duplicate or already existing subdomain/name. (who you entered before)
