 * Hi I’m having a strange problem with backups not working, a curl error and a 
   sprintf error. It can’t be the server since I’ve got other WordPress sites on
   that server which are using BackWPUp and other things (Dropbox/Mega uploading
   scripts, rclone) using Curl fine, it’s just this site.
 * I also get a sprintf error: Warning: sprintf(): Too few arguments in /wp-content/
   plugins/backwpup/inc/class-page-settings.php on line 87 when I go to the Settings
   page – which doesn’t happen on the other sites.
 * Tried disabling all other plugins, using 2018 theme etc and using alternative
   WP Cron as mentioned here. Doesn’t fix it.
 * Here’s the debug info.

 * Hi [@timbearcub](https://wordpress.org/support/users/timbearcub/),
    This is a
   known issue, which happens on setting page only as you said and no worry, it 
   does not affect the functionality of BackWPUp. The warning will be fixed in the
   future update, thank you for reporting it!
