Hello, I have plesk 8.3.0 installed on a dedicated server in Hong-Kong, and I have a problem with an account on Plesk. Here is the exact error when I try to save the setup page after I changed the FTP account password: Error: Unable to update hosting preferences: system user update is failed: Unable to create system user: usermng: PAM password change failed: 20, Authentication token manipulation error Let me describe how I got this. 4 days ago, I had to create a new domain on Plesk. So I started the procedure, and to be sure I had the exact same configuration as our main and first domain on Plesk, I opened a new tab in Firefox to have in parallel the 2 settings. Once I had set everything up for the new domain, I saved. Then some time after (some minutes), I noticed the script had interverted the 2 login names for the domains, because there were 2 tabs open at the same time surely. So I removed the newly created domain and realized and deleted the user in the shell. Doing that, I think I really made things worse... now I can not at all change the FTP password and moreover I have several errors with PHP scripts called by cron jobs. If anyone can help on this matter, that would be greatly appreciated! Thanks in advance.
