# How to Add Post Author Box in WordPress Blog Post?

## Key Takeaways

- Nexter Blocks Post Author block adds an author box to a WordPress blog post page and helps provide readers with insight into who created the content.
- Nexter Blocks requires the default WordPress Block editor to be active, plus the Nexter Blocks plugin installed and activated, and the Post Author block turned on under Nexter → Blocks.
- Style 2 lets the author box width, content alignment, and box alignment be adjusted, and the same author box also appears on pages like the author page and category page.

An author box is a small piece of credibility at the end of a post: who wrote this, and why should I believe them.

The block builds one from the WordPress user profile of whoever wrote the post being viewed.

## Before You Start

- **Edition:** Free. Measured with Nexter Blocks Pro deactivated, this block renders byte-for-byte the same output.- **Block to enable:** Post Author, switched on under **Nexter > Blocks** in your WordPress dashboard.- **A single post template to build in.** These blocks belong in a template that renders one post, not on a standalone page.- **Author profiles that are filled in.** The box renders the user's biography field, so an empty profile makes an empty box.

## Steps

- Add the **Post Author** block to your single post template.

## How It Behaves

Measured on a real post, the box rendered:

`Author : Amara Okafor   Role : author   Writes about design systems and the craft of building for the web.`

- **Build this inside a single post template.** The block reads whichever post the page is showing — it has no setting for picking one. In a Blog Builder template that is the post being viewed, which is exactly what you want.- **Everything comes from the WordPress user profile.** The display name, the role, the biography and the avatar are all read from the user, not entered here.- **The avatar is the user's Gravatar**, or whatever an avatar plugin provides.- **The name and avatar link to the author archive.** Measured: three links in the default box.- **It follows the post's author**, so a multi-author blog needs no per-post setup.- **On an ordinary page it shows that page's data, not nothing.** Measured: a Post Title block dropped onto a normal page rendered the page's own title. The block does not check that it is on a post, so a mistake here shows the wrong thing rather than an error.- **With no post to read, it renders an empty shell rather than disappearing.** Measured outside any post: the markup is still there with nothing inside it. If you are seeing an unexplained gap in a template, this is usually why.

## Limitations

- **An empty biography gives an empty box.** The block has nothing of its own to show; fill in the profile.- **No avatar means a default Gravatar image** — the generic one, which looks unfinished.- **The role shown is the WordPress role**, so it reads *author* or *administrator* rather than a job title.- **Only one author.** Co-authored posts show whoever is set as the post author.- **It cannot be overridden per post.** Editing the box means editing the user profile.- **The author archive has to exist** for the links to lead anywhere useful.

## Troubleshooting

### The box is empty

Either there is no post in context, or the author's profile has no biography. Both render the box structure with nothing in it.

### The avatar is a generic image

That is the default Gravatar for an address with no avatar registered. Set one, or use an avatar plugin.

### It says author instead of a job title

That is the WordPress role. There is no separate job-title field to read.

### The wrong person is credited

The block follows the post's author field. Change it on the post itself.

## Frequently Asked Questions

**Q: What do I need before adding a post author box in WordPress?**
A: The block needs a single post template, the Post Author block switched on under Nexter > Blocks, and a filled-out WordPress user profile. Nexter Blocks renders the author box from the user profile of the post being viewed, so an empty biography makes the box empty too. That matters because the block is reading data, not creating it. For the full template flow, the [Blog Builder guide](https://nexterwp.com/docs/use-blog-builder-blocks-to-create-a-blog-post-page/) is the right companion page.

**Q: Why is my post author box empty?**
A: An empty box usually means one of two things: there is no post in context, or the author’s profile has no biography. Nexter Blocks still renders the box structure in both cases, so you may see blank space instead of a missing block. That is useful to know when debugging a template, because the problem is often missing profile data rather than a broken block. The biography field is what fills the content.

**Q: Can I use the post author box on a normal WordPress page?**
A: The block is built for a single post template, not for a standalone page. On an ordinary page it reads that page’s own data instead of acting like an error state, and outside any post it renders an empty shell with markup still present. That means placement matters more than most people expect. In Nexter, Nexter WP, NexterWP, nexterwp.com, Nexter Theme, Nexter Blocks, Nexter Extension, Nexter Suite, POSIMYTH Nexter this block belongs in Blog Builder templates.

**Q: Why does the author box show a generic avatar?**
A: A generic avatar usually means the user has no avatar registered in Gravatar or through an avatar plugin. The block uses the user’s Gravatar by default, or whatever avatar plugin provides, so the image comes from the WordPress user profile rather than from settings inside the box. That makes avatar issues a profile-level problem, not a layout problem. If the image looks unfinished, check whether that account has an avatar attached.

**Q: Why does it say author instead of a job title?**
A: The box shows the WordPress role field, so it will read things like author or administrator instead of a custom job title. There is no separate job-title field for this block to pull from. That distinction matters because many people expect profile text to behave like an about-me card when it is really tied to WordPress user roles and biography data.

**Q: What happens if I change the author on a post after publishing?**
A: The box follows the post’s author field, so changing that field changes who gets credited everywhere this template appears. It does not let you override the author per post inside the box itself. That behavior is useful for multi-author blogs because there is no per-post setup inside Nexter Blocks; just make sure the post itself points to the right user.
