Log in to Plesk GUI
Go to Domains > example.com > PHP Settings > Select a PHP version handled by FastCGI > Scroll down to FastCGI Settings > Set the option Enable FastCGI Settings to On > Click OK to apply the changes

Workaround

Fixing permissions in order to access files via Plesk File Manager / FTP

Connect to the server via RDP
Start a command prompt as an Administrator
Run the command:

C:> plesk bin repair --repair-webspace-security -webspace-name example.com -all-filesystem-objects

Fixing permissions before creating a manual server Plesk backup

Connect to the server via RDP
Start a command prompt as an Administrator
Fix file permissions:
- For one domain
  
  C:> plesk bin repair --repair-webspace-security -webspace-name example.com -all-filesystem-objects
- For all domains
  
  C:> for /f %i in ('plesk bin subscription -l') do plesk bin repair --repair-webspace-security -webspace-name %i -all-filesystem-objects
Create a full Plesk backup.

Fixing permissions before creating scheduled server Plesk backups

Warning: The following workaround must be applied every time after applying the changes at Tools & Settings > Backup Manager > Schedule, because the task is overwritten.

Log in to Plesk GUI and schedule a full server backup:

1.1. Go to at Tools & Settings > Backup Manager > Schedule >

1.2. Enable Activate this…
