Hello, i want to import the backup file from ciphermail 4.11 (CentOS7) to a ciphermail 4.11 (ubuntu 20.4). Unfortunately it doesn't work. After clicking on the "restore buckup" button it comes an error the page cannot be reached ( https://xxx.xxx.xx.xx/ciphermail/admin/backup/create.form).
What do i have to do? Best regards Jürgen Weppert
