Well, now nothing works. I tell it to do a backup, it says "Requesting start of backup..." then "Security check" then nothing happens.
It does say "Backups, logs & restoring: 1 set(s) available" from 11/26 and I did receive an email last night saying
UpdraftPlus: WordPress backup is complete.
Backup contains: Files and database
Latest status: The backup apparently succeeded and is now complete
ETA: I closed the tab then reopened the Settings and now it's creating file backup zips.
