Hi,
It seems like I’m having the samw problem here, and I don’t get the white space warning either. I did try to deactive all the other plugins just to be sure. When trying to unzip the file I get “… not in gzip format”. As David said it doesn’t seem like it is decrypted. I checked the updraftplus log for that session and the last part of it is not readable at all.
Did you find out what the problem really is?
