I’ve updated to version 12.01.26 but I’m still getting a blank page when I use the manual backup and no backup is performed. Sounds just like what alisonmonahan was experiencing. The difference being background backups do work for me.
Further the automated backups aren’t working at all.
Thanks for your help, hopefully we can get these kinks ironed out since I love the simplicity of your plugin and wish to continue using it.
