As previously stated this appears to be a generic error message.
For info I have had this problem when an account has been created with a user role which the operator is not allowed to approve (as defined in their operator profile).
This suggestion was a great help and was the exact reason I was getting the same message.
I had my operator profile set to only create guests with [Employee] but in the self-registration page, the role-id field was set to 2, which maps to [Guest].
Thanks
