Edit Author Slug

On standard WordPress installs, it’s the final part of an author permalink.
e.g. – https://example.com/author/author-slug/

In relation to WordPress internals, the author slug is the same as the user_nicename field found in a WP_User object, or the users table in the database.

It depends.

Changing a user’s author slug is permanent, as this changes the user’s user_nicename field in the database.

If you’ve changed the author base, deactivating or deleting the plugin will revert your author base back to author.

Make sure you are an admin, or have been assigned the edit_users capability.

While I’ve made every attempt to prevent this, I may have missed a spot or two. First things first, go to Settings > Permalinks and click “Save Changes.” You don’t need to actually need to make any changes for this to work. Hopefully, this should kick your new Author Slug into gear.

If this doesn’t work, make sure you don’t have any slug conflicts from other posts/pages/plugins/permalink setting/etc. If you’re still experiencing the issue, feel free to post a support request in the forums.
