Bug description

When attempting to set the default authors for blog posts via the meta plugin according to the docs, the authors do not actually show up on the blog posts. Non-blog metadata configured via the meta plugin (such as tags) will show up, so properties from the meta plugin are being applied to the file, but seemingly blog data is not.

This can be worked around by manually copy/pasting the meta contents into the frontmatter of each post.

  • Another user is encountering the same issue but did not provide a reproduction for it. Based on the git history of the repo they linked, they are still encountering the issue / have not yet removed their workaround for the issue.

Reproduction

9.4.7+insiders.4.42.3-meta-doesnt-set-authors.zip

Steps to reproduce

1. Install dependencies
2. Build the site with mkdocs build or serve it with mkdocs serve
3. Navigate to the blog index. Observe that the post with the author explicitly set shows an author, but the post which should be using the author from the meta does not have an author shown.
4. Navigate to the post without an author shown, and observe that there is a "Blog" tag shown at the top, showing that the meta file which should be configuring the author is applying to this file.
