Snapshot Pro / Error: Manifest data not found in archive.

Hi,

I have looked and tried solutions to fix, Error: Manifest data not found in archive. on a multisite when importing a zip file from another server install.

I have tried, dropbox/google drive/direct URLs aswell as uploading the zip files locally and still get the same Error: Manifest data not found in archive error.

I have enabled support access to the site.

Thanks in advance.
