You use Simple Author Box to show author bios. Guest posts show your name instead of guest name. That is frustrating because guest authors get no credit.
A common issue is that Simple Author Box pulls author from WordPress user account. Guest posts are often written by users without accounts. Plugin cannot find guest author. It defaults to post creator (usually admin). The plugin is not broken. Guest authors need user accounts.
Why Simple Author Box Shows Wrong Author
Simple Author Box gets author information from WordPress user ID. Every post has an author ID (the user who created it). If guest author does not have WordPress account, post is created by admin. Author ID is admin. Plugin shows admin bio. Guest author is ignored.
This is not Simple Author Box being bad. Guest authors need user accounts.
The Most Common Wrong Author Scenarios
- Guest post submitted via form (no user account)
- Post imported from another site (author ID lost)
- Admin created post on behalf of guest (author = admin)
- User account deleted but posts remain (author = deleted user fallback)
- Co-authored posts (multiple authors, plugin shows one)
Each needs different fix.
How to Fix Author Box for Guest Posts
- Create WordPress user account for each guest author
- Assign guest posts to that user (not admin)
- Edit post → Author dropdown → Select guest user
- Update post
- Simple Author Box will show guest author bio
Guest authors need accounts. No way around it.
How to Add Guest Author Without Giving Dashboard Access
Create user account with role “Author” or “Contributor.” These roles can only write posts, not access settings. Guest can log in, write post, but cannot break your site. Safe.
If you do not want guest to log in, write post yourself and assign author to guest user. Guest never logs in but gets credit.
Alternative: Use Co-Authors Plus Plugin
Install Co-Authors Plus. It adds guest author functionality without user accounts. Simple Author Box supports Co-Authors Plus. Guest authors appear correctly.
Co-Authors Plus creates virtual guest author profiles. No login needed.

Final Thoughts
