Visual editor broken after import from snapshot into multisite


I have an issue with Snapshot imports on a multisite.

The multisite has been functioning correctly with several sites.

I installed domain mapping

I created a snapshot on an external domain

I imported (after creating and mapping a subdomain) the snapshot of the external domain.

Now…some posts are blank.

I have no information in the visual editor tab and it does not seem to be functional.

The 'text' tab has all the original information in the original post but the post is blank in the front end.

The 'disable text editor' checkbox has been switched on and off several times.

All other subhumans are fine. (there is a working visual editor)

Please advise how I rectify this.

Thanks guys.
