OS X Server 5 WebDAV Error

I am running DTPO on El Capitan. I am trying to set up a WebDAV server on a Mac Mini running El Capitan and OS X Server 5. I get through the authentication, and the items are processed. However, at the very end, I get two error messages in the log:

Could not read the receipt.

Could not commit the transaction (Could not merge the directories (Could not merge the directories (Could not move a file/directory (File not found.)), Could not merge the directories (Could not fetch the type of a file/directory (Could not fetch the itemÕs type because no such item exists.)), Could not move a file/directory (File not found.)))

The resulting sync file cannot be imported into another copy of DTPO.

I have tried this with a new, empty database, so I do not think it is a data problem.

Has anyone else seen this, and is there a fix?

Regards,

Michael
