Until yesterday shell users worked fine. Then I had to rename a user and the problems started. Using Webmin I noticed that renaming a user with ISPConfig 3, the old one is not deleted so I deleted via Webmin, what a mess. Now, even creating new shell-users, no longer work. The situation is this: a client with multiple sites for each site I create a shell-user to allow access to the site folder through SFTP. Can anyone help me to solve?
