I’ve tried wiping the updraft plus details but no luck. I’ve tried activating and deactivating no luck.
I get a message

Congratulations! Your first backup is running.
But to avoid server-wide threats backup regularly to remote cloud storage in settings

I’m using the latest updraftplus. It’s on a linux server. My host support says that there’s no problem with the server. The backup file is writable. There’s 8KB used in the updraftplus backup folder on the host server ( where i’m saving the backup).
