Enable WordPress Author-Info Box on Single-Author Blogs

WordPress has a built-in author-info box that displays your bio, avatar, and website at the end of posts. By default, it only appears on multi-author blogs. Here’s how to enable it on single-author blogs without plugins.

Why Enable It?

Displaying your author box makes your blog look more professional and provides quick context about your expertise—especially useful if your theme includes enhanced author box features.

Method 1: Database Edit

• Fill in your WordPress profile “Biographical Info” (Users → Your Profile)
• Open phpMyAdmin from your hosting control panel
• In the wp_options table, search for _transient_is_multi_author
• Change its option_value from 0 to 1
• Clear your cache and view any post—the author box should appear

Method 2: Theme Function

Add this to your theme’s functions.php:

add_filter('is_multi_author', '__return_true');

Note: Use a child theme so updates don’t remove this code.

Troubleshooting

• No author box? Your theme may not support it. Test with a default WordPress theme to verify.
• Profile incomplete? Ensure “Biographical Info” is filled and upload a Gravatar image at gravatar.com.
• Custom prefix? Your table might be wp_xxxxx_options instead of wp_options.

Conclusion

Both methods work well—the database edit is cleanest, while the theme function persists through WordPress updates. Remember to backup your database and complete your profile before enabling.
