Cause

%plesk_vhosts%\example.com\.plesk\.Security is corrupted for the subscription.

Resolution

1. Rename the.Security file:

   C:\> ren "%plesk_vhosts%\example.com\.plesk\.Security" .Security.old

2. Repair file permissions for the subscription:

   C:\> "%plesk_cli%\repair.exe" --repair-webspace-security -webspace-name example.com
