Hello. Debian 11 (Bullseye) + ISPConfig 3.2.7p1 I create new FTP user via ISPConfig UI. I entered the wrong FTP home folder. I accidentally created a folder: /var/www/clients/client1/web1/web01 I delete this FTP user. But the folder didn't delete itself. I tried as root: rmdir web01 result: Operation not allowed rm -rf web01 result: Operation not allowed ls -lha drwxr-xr-x 2 web1 client1 4,0K 20. lis 20.08 web01 chmod -R root:root web01 rm -rf web01 result: Operation not allowed I restarted the server and tried to delete the folder again. Without success. How do I delete the folder?
