I also have the blank page issue.
It seems that you can conduct only one successful backup manually. If they are unsuccessful (for exemple because of a bad configuration of google drive, as I did) I can relauch it as many time as I want. But if one of this backup is successful the blank page issue appears and I cannot make any manual backup any more.
But I have scheduled a backup during the night at 3am, it was launched at 9am this morning (6 hours after the scheduled time and 8h40 after my first successful backup). Then it was the same problem : I could only make one successful backup manually.
What’s wrong with it?
Is there a parameter which prevent to do 2 backups in the same day? in the same week? or something like that?
thanks
