Hi,
I am one of your reseller, I am getting the following error message, when I am trying to singup an account:
“Failed to create Account. The previous request for the user creation has been locked in. If it failed, try to sign up from scratch.”

If a signup fails, it is added to the list of Accounts to be moderated (the Signup section). In this case, all you need to do is delete this account in the list and re-try the signup. If the account is not in the list, simply close the signup wizard and re-try the signup from scratch.
