• Ghost Version: 2.16.4

Importer is a labs feature (experimental). IMO we can release the fix and the enhancements #10585 on Tuesday. The import is only broken if you export on 2.16 and import on 2.16. I will add a note on the release.

Yes, I had the same issue to with 2.16.4
Upgrading fixed the problem.
