Can't use 'author' as a custom taxonomy name

[nathanshubert]

I tried creating a custom taxonomy called 'author'. When using wp_tag_cloud or get_terms I got a list of terms with links, but the links would either take me to an empty archive page, or one with just a couple of the posts with a term from that taxonomy. As soon as I changed the taxonomy name from 'author' to something else everything was fine. Looks like there's a bug involving using 'author' as a taxonomy name.

The name 'author' is a ​reserved term as it's used internally by WordPress. You could try something like 'authorname' or 'bookauthor'.
