So I finally decided to upgrade my VPS. I backup using "Backup/Restore" feature. Working perfectly and downloaded the backup. But when I used "Backup/Restore" to restore on the new VPS it didn't work.
I selected the file to restore it just blank. So I tried to add the path myself "/home/kloxo/client/admin/__backup/my-backup-file.tgz" and got this error.
Alert: Could not find file [__path_program_home/client/admin/__backup/homekloxoclientadmin__backupmy-backup-file.tgz]
I also check on my old VPS running 7.0.0.b-2016062202 and when I selected the file the input path also go blank.
