Hello, On my server I have installed the version 18.104.22.168 of ISPConfig. I created a Shell-User for a particular site and everything worked normally. Therein, I noticed that some folders were created inside the folder of the site, such as bin, dev, lib, lib64 and others. After testing, I delete users (Shell-User), and the folders remained. As root, I try to delete these folders with the command "rm -rf bin" and returns the error "rm: can not remove` bin ': Permission denied". When creating a user, I selected the Chroot Shell Jailkit I've tried several ways (chmod, chown, chattr -i), but it still fails. I need help. Thanks!
