Error trying to manage MSP Business Rule

Error trying to manage MSP Business Rule

Hi,
when i try to accesso to MSP Business Rule page, i get this error:
 "All sites in the selected account refer to 'Default Settings'. Only an administrator can create or modify configurations for 'Default Settings'. He can do this by selecting 'All Accounts' in the account combo-box and 'Default Settings' as site"
(see attached file).
I have admin user, and i also tried with ADMINISTRATOR user but the problem is the same.
How can i fix the problem?
Thanks.
Best regards.
