Hi,

trying to complete the challenge, I have the following error:
The "Customer Community User" for the contact "Edna Frank" is not created properly.

More info, hope this helps finding the problem:
The contact exist, in Admin > Users> User license is "Customer Portal Manager Standard", when I try to change it to "Customer community" i'm getting the error "cannot upgrade from or downgrade to LPU"
The contact is assigned to the account "Customers", there is a case associated to it, with Contact Name = Edna Frank
I created the Sharing Set Settings and configured the access (User:Account = Case:Account, Read/Write). The community is active.
Oddly enough, I cannot log in as Edna Frank.
If I'm trying to create a new user, I receive the following error: "Your request cannot be processed at this time. The site administrator has been alerted.
The account associated with this portal has no owner". The created account is "Customers" and I double checked, i'm the owner of this account.
I've received a message "Customers registration accountId parameter value is not valid."

Any idea or clues on how to solve this ?
