@bcrodua I have no log to show. It shows my last successful backup in the “Existing Backups” section as December 10th. I only auto backup my site once a week, so that means the last 3 times it hasn’t worked for me. (Dec 17, 24, 31)
It’s not showing any backup attempt for the last three weeks, successful or otherwise in that section. So for me, the scheduler kicks in once a week, I get an email saying the backup was made (but with the above error message), and that’s it. It doesn’t save anything anywhere.
I haven’t changed anything on my site like add new plugins or whatever. I had an issue with your plugin a few months ago where it stopped dumping my backups to Dropbox for the same type of problem. It said it backed up but never sent it. I switched it over to FTP and it was working again, till now.
