Hello.

I have been using jbackup for a while, and it runs smoothly, and I'm getting daily emails.
I have more than one site on this server, and they all run well.

I once un-installed jbackup for a while, and then installed it backup.
It now works (takes backups and puts them on the server), but does not send me the database by email

Please see an attached image with my settings.

What should I do?

Any help?!

Is it the same as the server that worked smoothly?
Moreover, is the setting also the same?

Yes. The same server, and the very same settings.
I tried using another email address, but to no avail.

Can you have a look at the settings screenshot in my first post.
All all settings optimal?

Is there anything to change to make it work?

Thanks.

There is no problem in your setting.
And no problem in my site and other.

Please try the following file(new beta).

Setting for test email sending
1. Only cron to Yes (default is No)
2. Click Execute Cron Link
