# Website Environment

The website environment configuration setting changes what data your website displays, and how it behaves.

## Production Environment (ENV\_PROD / 1)

Production Environment hides any advanced diagnostic information or errors from the frontend website and fatal error pages such as your PHP version, server operating system, server software, and server port on error pages.

## Development Environment (ENV\_DEV / 0)

{% hint style="danger" %}
You should **never** have your website set to development environment if it is live to visitors on the web.
{% endhint %}

Production Environment displays advanced diagnostic information on Saturn's fatal error pages such as your PHP version, server operating system, server software, and server port on error pages.

This setting also unlocks settings that require a development environment.
