Sometime while creating Additional FTP account or Updating Domain user it shows following Error
Error: Unable to update FTP account: Unable to create web user: Update FTP user failed:
ftpmng --add-user failed: Empty error message from utility.
This problem comes when .Security file of the domain get corrupted. This file can be found at
C:Inetpubvhostsdomainname.com OR D:Inetpubvhostsdomainname.com OR in the domain home directory. Rename the file to OLD.Security and run following command:
C:ParallelsPleskadminbin>websrvmng.exe --reconfigure-vhost --vhost-name=domainname.com
OR
C:> "%plesk_bin%ftpmng.exe" --reconfigure-vhost --vhost-name=domainname.com
Above command will create a new .Security file based on the Plesk Database and then try to create new FTP user or try to update domain user.
