Cause

Plesk product bug #EXTWPTOOLK-1861 which will be fixed in future product updates.

Resolution 

Log into Plesk and apply one of the following workarounds:

• Manually create a subdomain under "example.com", e.g. "staging.example.com", and clone the WordPress instance to this subdomain.
• Go to Subscriptions > example.com > Customize > Permissions tab and enable both "Domains management" and "Subdomains management" permissions.
