User profiles showing 404's in byline

I am currently in the process of migrating a WordPress to Ghost using the guide.

It is working as well as I think I can expect it to.

The problem I am currently running into is the byline on a post correctly shows the author’s name, but the link is a 404.

You can see in the image below the link preview in the bottom left. This is shown on the main page as well as on the post itself.

I can manually go to /author/:author_name and it works fine.

I noticed this is happening for all author’s except for the admin user that was used to import the export file.

The only differences in user’s i can see is that the admin user has an integer id (1 in this case) and the rest have uuid’s.

Any ideas?

I went ahead had attempted to see if updating from 1.x to 2.x would fix it and it seems to have done that ¯_(ツ)_/¯.
