Hosting is disabled on a domain.
On the domain overview page, Advisor icon is still showing.
Advisor advises are actual for domains with hosting only and extension cannot provide any applicable advice for no-hosting domains.
Advisor extension bug #EXTADVISOR-520 that is planned to be fixed in future extension updates.
Until the bug is fixed, the only workaround is to disable Advisor completely. for that:
Log into the server via SSH.
Execute the following command to disable the extension:
# plesk bin extension --disable advisor
Note: for windows, command is exactly the same.
