<p>Author by Category helps news websites and multi-user blogs keep post authors consistent without disrupting the editorial workflow. The plugin is not limited to authors. <strong>Administrators can assign any user — including editors, contributors, or themselves — to any category.</strong></p>
<ul>
<li>Create simple rules that connect categories to specific users.  </li>
<li>When a post is saved with those categories, the plugin can automatically assign the author.  </li>
<li>If an editor changes the author manually, their choice is always remembered.  </li>
<li>This prevents posts from being published under the wrong name by accident.</li>
</ul>
<h3>Key Features</h3>
<ul>
<li>Works with any user — not just authors.  </li>
<li>Admins can assign any user (editor, contributor, etc.) to any category.  </li>
<li>Manual author selection is always allowed and remembered.  </li>
<li>Rules can include multiple categories; first match wins.  </li>
<li>Duplicate guard: one category can only be used in one rule.  </li>
<li>Optimized for large sites with many users.  </li>
<li>Secure: follows WordPress coding standards (nonces, capability checks, sanitization).  </li>
<li>Compatible with scheduled posts, REST publishing, PHP 8, and the latest WordPress versions.</li>
</ul>
<h3>Best Practice for Performance</h3>
<p>For smooth scheduling and zero-maintenance cron execution, we recommend hosting your WordPress site on <a href="https://ihost.eco" rel="nofollow ugc">ihost</a> WordPress Cloud Hosting.<br />
See FAQ <span aria-hidden="true" class="wp-exclude-emoji">→</span> Recommended Hosting for an <strong>ihost-optimised <code>php.ini</code> template</strong> you can copy and paste.</p>
<h3>Compatibility</h3>
<ul>
<li>Scheduled posts: applies the correct author at publish time.  </li>
<li>REST/remote publishing: ensures the correct author after categories and content are set.  </li>
<li>Designed for large editorial teams.</li>
</ul>
<h3>How It Works</h3>
<ol>
<li>Go to <strong>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Author by Category</strong> and create rules that match categories to users.  </li>
<li>When a post is saved or published, the plugin checks which categories are selected.  </li>
<li>If a matching rule is found, the post author is updated automatically.  </li>
<li>If an editor changes the author manually, the plugin remembers that choice for future posts with the same categories.</li>
</ol>
<h3>Privacy</h3>
<p>This plugin does not collect, store, or share any data.</p>

Edit Flow

I have a fresh install with no plugins and Twenty Seventeen and I get this error when I try to activate the plugin: 

The plugin does not have a valid header.

Is this plugin dead?

Unable to Activate

Great plugin, logical interface. But there are two huge downsides:


	No active support from the developers
	It does not work on Gutenberg


So if you're not working with Gutenberg (which will be the default editor in WP 5.0) and you have no need for support: go for it! Great plugin!
In all other cases: find something better, and let me know what you've found, I need a replacement as well ;)
