Snapshot Error: Manifest data not found in archive.

Hi,

I'm getting the following error when trying to migrate a snapshot from a subsite to a single WordPress site:

Snapshot Error: Manifest data not found in archive.

I've tried many possible solutions from the forum but didn't help. Can you guys create a snapshot from this subsite "timdenniston.creativezombie.com" and then try to restore that snapshot on a single WordPress site?

What am I missing?
