Environment Indicator adds a prominent visual indicator to the WordPress admin bar showing the current site environment. This high-visibility indicator helps prevent accidental changes on production sites by making the environment instantly recognizable to logged-in users.
Perfect for developers, agencies, and teams managing multiple environments (development, staging, production) across different sites.
<h4>Key Features</h4>
Smart Environment Detection 
* Automatically detects environment using WordPress core constants (<code>WP_ENVIRONMENT_TYPE</code>) 
* Supports popular hosting providers: WP Engine, Pantheon, Kinsta, Flywheel 
* Legacy Bedrock constant support (<code>WP_ENV</code>) 
* Subdomain-based heuristics (dev.example.com, staging.example.com) 
* Manual override option for custom setups
Customization Options 
* Custom Colors – Match your branding or personal preferences for each environment 
* Custom Labels – Rename DEV/STAGING/LIVE to LOCAL, UAT, PRODUCTION, or anything you prefer 
* Role-Based Visibility – Control which user roles can see the indicator (great for client sites)
Visual Enhancements 
* Admin bar label (always visible) 
* Full admin bar background coloring (high-visibility option) 
* Browser tab prefix – instantly identify environments across multiple tabs 
* Top border in wp-admin screens 
* Admin footer watermark 
* Dashboard widget showing environment status and system information
Export/Import 
* Export settings as JSON to deploy across multiple sites 
* Import settings from JSON file 
* Perfect for agencies managing client sites with consistent configurations
Multisite Compatible 
* Full support for WordPress multisite installations 
* Network-wide settings when network-activated 
* Per-site settings when activated on individual sites
<h4>How It Works</h4>
Detection runs in this order:
<ol>
<li>WordPress core constant: <code>WP_ENVIRONMENT_TYPE</code></li>
<li>Legacy constant: <code>WP_ENV</code></li>
<li>Hosting provider constants (WP Engine, Pantheon, Kinsta, Flywheel)</li>
<li>Subdomain patterns (dev, staging, test, qa)</li>
<li>Default to LIVE if no detection</li>
</ol>
You can always override automatic detection and manually select the environment.
<h4>Perfect For</h4>
<ul>
<li>Developers – Never accidentally deploy to the wrong environment</li>
<li>Agencies – Manage multiple client sites with consistent environment indicators</li>
<li>Teams – Everyone instantly knows which environment they’re working in</li>
<li>Managed Hosting – Works out-of-the-box with WP Engine, Pantheon, Kinsta, and Flywheel</li>
</ul>
<h4>Zero Impact on Visitors</h4>
The indicator only displays for logged-in users. Public visitors see no performance impact or visual changes.

This plugin creates a custom post type for theater productions with taxonomy for actors, venues and more. It’s intended to be used by theater associations, NGO:s presenting theater productions etc. It will hold the information about a theater production together with taxonomies to make it easy to create events. Included are template files that you can use to create your own templates for your own theme to customize how the information is showed. 
The template files will work with the theme “Beyond-expactations”, but are merely provided as guides to make your own template files. If you dont use the templates your theme should be able to show the information about the event, but it might miss some of the taxonomies. 
The plugin is a part of the <a href="https://ngo-portal" rel="nofollow ugc">NGO-portal</a> project. You can find the code at <a href="https://github.com/joje47/NGO-portal" rel="nofollow ugc">GitHub</a>.
