Cause

Incorrect permissions on %plesk_vhosts%example.com\.plesk\.Security.

Resolution

1. Connect to Plesk server using RDP.
2. Rename or remove the %plesk_vhosts%example.com\.plesk\.Security. file.
3. Restore domain file and folder permissions using via command line:

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

   To restore it for all domains, execute below commands:

   C:\> plesk db -Ne "select name from domains where htype='vrt_hst'" > C:\domains.txt

   C:\> for /f "tokens=*" %d in ('type C:\domains.txt') do "%plesk_cli%\repair.exe" --repair-webspace-security -webspace-name %d -all-filesystem-objects

4. If this did not help, add required permissions on the folder mentioned in the error in %plesk_dir%admin\logs\php_error.log: psaadm user must have List folder content for this folder and subfolders and Read for files only permissions:
