DNN displays "User updated successfully" when the default superuser account username is changed, but the value in the database for the default superuser account username remains unchanged.
- Add a new superuser account using the desired credentials.
- Log in as the new superuser and confirm that the account is working as intended.
- Disable the old "host" account.
Note: If needed, you can manually reenable the old host account by directly accessing the database. Use the following query:
update users set IsSuperUser=1 where username = '/*username goes here*/'
