I could not log in to Plesk Panel because of the error message:
No SP with id=b9awiut22ogelhza3tlu0kp35dtrt74qdqa
SSO integration is broken or Customer and Business Manager was not fully upgraded.
Complete the upgrade of the Customer and Business Manager by running autoinstaller with the following options:
/usr/local/psa/admin/bin/autoinstaller --select-release-current --upgrade-installed-components
"%plesk_bin%\\ai.exe" --select-release-current --upgrade-installed-components
