Automatically FTP backup script no more working in cPanel versions 11.40+

Hello,

I was using for years a script in order to backup my accounts to a local FTP server. Noticed that with the new features of cPanel like security questions and more... As I've checked the backup script, it doesn't return any error at all, but it also doesn't run. I had a look at this script and apparently it works by connecting to cPanel and sending it a request to start a backup process. I'm pretty sure that it doesn't work due to compatibility reasons with the new cPanel version.

The script i'm talking about, you can found it here.

I also check with an updated version from here with no any luck.

So can you please tell me where the issue is?

Thank you.
