I dont know if this helps, what I did was login to the file manager/ftp directory of my hosting then go to wp-content/backupwordpress-xxxxx-backups
I then go to the wordpress admin page and click on Tools/Backup and Run Backup manually (Run Now)
I then go to my file manager/ftp directory and refresh the page, I then see 2 files get created
backup-XXX-running
XXXXXXX
Now if I refresh I can see the XXXXX file size changing (when you are on the worpdress plugin page it shows the approx size) so I just wait for it to finish and then press refresh, now the 2 files are
backup-XXX-running
XXX-XXX-1461259607-database-xxxx.zip
now I just delete the
backup-XXX-running
and refresh the wordpress plugin page.
It shows the backed up file and the spinning has stopped
I have disabled the scheduled backups
I also had the same problem, but I don’t know whether my solution would work for you or we have the same problem, anyways what I did was I removed any dashes “-” from the Subject Line and voila everything started working again. Although I also saved the Subscribe2 options again (just went to Tools>Subscribe2 and saved the options again without any changes). Hope you can sort it out.
ciao
