Cause

Incorrect VHOST paths in the database and Windows registry. Plesk Reconfigurator changed paths in psa database and Windows registry but due to an error, all the files and domain content are still in the old VHOST path.

Resolution

1. Connect to the server via RDP

2. Backup psa database:

   plesk db dump psa > c:\psa.sql

3. Repair paths with the following command:

   plesk repair db -v

4. Open registry editor and change the path for HTTPD_VHOSTS_D value at Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\PLESK\PSA Config\Config
