If first post on an author archive has multiple authors, the archive's heading displays both authors' bios.

Should I show only 1 author? Is it the owner of the author's page? I would like to help you with this, but I would need a copy of that site to have a real environment, if possible.

The author that should be displayed in this area is the author for the archive page.

I can't give you a copy of that site's database, but you could replicate the issue by:

1. installing the Co-Authors Plus plugin
2. Creating a Co-Authors Guest Author, with bio in the user profile
3. Creating a WordPress User, with bio in the user profile
4. Creating a post as the WordPress User, and choosing as Co-Authors on the post both the WordPress User and the Guest Author
5. Visiting the WordPress User's author archive.

As you can see in the image, I think I have replicated the problem.

user: long
co-author: "Co author"

Now you want that in each post only the name of the main author comes out? in this case "long" and do not leave the invited authors, only the owner of the publication?

The result would be the following:

2fcd2a1 prevents the additional author from being output in each story's byline, which does not address this issue.

I admit that I didn't describe this issue as fully as could have been done. The problem is that there are two authors' biographical information being output at the top of the post archive by the Largo Author Widget's code, when there should only be one because this is a single-author archive.

The archive template calls the Largo Author Widget:

https:/INN/largo/blob/72cc8433a1be1de4f22789e1ec89496d54a653d9/archive.php#L97-L99

Which in turn loops over the list of authors in the current post in The Loop.

https:/INN/largo/blob/025169a6b2ba90da97093b3005cbbadf40667291/inc/widgets/largo-author-bio.php#L61-L74

Because the current post in the Loop may have more than one author, in situations where the current post in the Loop has more than one author, the widget outputs both authors' bio instead of outputting only the bio for the author whose archive page is being viewed.

It should output only the bio for the author whose archive page is being viewed.
