Governance Guardrails is a file-based WordPress governance plugin for site owners, agencies, and managed WordPress teams that want important operational rules to live in code instead of scattered database settings.
You define a policy in a PHP configuration file. Governance Guardrails reads that file on each request and applies the configured rules. This makes the policy easy to review, version-control, and deploy consistently across environments or multiple sites.
Governance Guardrails can help you manage:
<ul>
<li>Feature toggles such as XML-RPC, comments, feeds, the Customizer, widgets, application passwords, user registration, WP-Cron, and related admin features.</li>
<li>Admin UI cleanup, including admin bar nodes, dashboard widgets, menu pages, and admin footer text.</li>
<li>Runtime capability denials by role without changing stored role definitions in the database.</li>
<li>Upload governance, including allowed MIME types and per-file size limits.</li>
<li>Content behavior such as revisions, autosave intervals, oEmbed, and emoji loading.</li>
<li>Login behavior such as password reset restrictions, generic login errors, and post-logout redirects.</li>
<li>HTTP security headers and other hardening options such as pingback removal, author archive handling, file editing restrictions, and staging noindex headers.</li>
<li>Head cleanup for RSD, WLW manifest, shortlinks, feed links, and REST API discovery links.</li>
<li>Locked options so selected <code>wp_options</code> values are pinned from code.</li>
<li>Custom governance callbacks for site-specific rules.</li>
</ul>
This plugin does not claim to secure a site by itself. It is intended as a governance and consistency tool that helps keep selected WordPress settings and behaviors aligned with your site’s operational policy.
<h4>Must-use plugin support</h4>
Governance Guardrails was originally built for must-use plugin deployment. It can still be installed that way by copying <code>governance-guardrails.php</code> and the <code>governance-guardrails/</code> directory into <code>wp-content/mu-plugins/</code>.
For WordPress.org installation, it can also be installed and activated as a normal plugin. In that case, the included sample config is used from the plugin directory unless you define a custom config path.
To use a custom config file, add this to <code>wp-config.php</code>:
<pre><code>define( 'GOVGUARD_CONFIG', '/absolute/path/to/governance-guardrails-config.php' );
</code></pre>
The shipped sample config lives at <code>governance-guardrails/governance-guardrails-config.php</code>.
Config loading is fail-open. If the config file is missing, unreadable, has a syntax error, or does not return an array, Governance Guardrails does not enforce governance rules and logs a warning instead of crashing the site.
<h4>WP-CLI</h4>
When WP-CLI is available, Governance Guardrails registers the <code>wp governance</code> command set.
Examples:
<ul>
<li><code>wp governance status</code></li>
<li><code>wp governance check</code></li>
<li><code>wp governance audit</code></li>
<li><code>wp governance audit --severity=high</code></li>
<li><code>wp governance diff</code></li>
<li><code>wp governance get features --format=json</code></li>
<li><code>wp governance mimes</code></li>
</ul>

A simple plugin that lets you add your custom CSS to style the WordPress Admin. Works with WordPress single install and WordPress multisites.
Version 2.0 is updated wtih an Admin interface and can be found in Appearance > Admin CSS MU
Admin CSS MU uses CSSTidy to clean and optionally minify CSS. CSS is only minified while using it. The editor always shows un-minified CSS for easy editing.
Note: If you want to easily add custom CSS on your Login and Front-end as well (along with WordPress Admin), use my <a href="https://wordpress.org/plugins/custom-login-admin-front-end-css-with-multisite-support/" rel="ugc">Custom Login Admin Front-end CSS</a> plugin instead.
