Hi I am trying to import content from a different CMS and assign these imported posts the correct guest author during import (using WP All Import) to WordPress. Everything works except assigning co-authors. I have tried associating the correct information on import to the following custom fields cap-display_name and cap-user_login , but my guest author does not associated to my imported post. Also, I did not try cap-linked_account because my guest author does not have a linked account. He is just a guest.
Some more info. The guest authors are already in my WordPress. I am not trying to import the guest authors, but just trying to import the post and associate the guest author to that post during import.
Any help would be greatly appreciated. Thanks.
