This plugin gives you full control over the permalinks for author pages. When using “pretty permalinks”, by default URLs to author pages are structured:
http://www.example.com/author/author-name/
With this plugin you can change the “author” part of these URLs into anything you like, for example:
http://www.example.com/editorial/author-name/ 
http://www.example.com/crew/author-name/ 
http://www.example.com/members/author-name/ 
http://www.example.com/posts-by/author-name/
The plugin will also automatically change links throughout your site that point to author pages. The URLs of author feeds are also changed.

<h3>Yoast SEO specifics</h3>
If you’re using Yoast SEO plugin, after you change something in the Remove CPT base plugin, you should deactivate Yoast SEO and activate it back again to refresh its yoast_indexable database table, so it will generate correct og:url, canonical url and JSON-LD urls.
