Comment (by karthikeya01):

 Hello @leedxw

 Thanks for reporting the issue.

 I believe this should be fixed in the `Co-Authors Plus` plugin. The plugin
 modifies the `$wp_query` in the `fix_author_page` method in `class-
 coauthors-plus.php` when querying guest authors, and the warnings appear
 only for guest authors, not for normal users. When we visit
 `http://localhost:8889/author/guest_author/?cat=1`, the initial
 queried_object represents `cat=1` and is_category is true, but the plugin
 changes it to author. Therefore, setting `is_category` to false inside the
 function should resolve the issue.
