# Developer Settings

Developer Settings provide tools for debugging, maintenance, database access, and PHP version management. These settings are found under **Advanced → Developer Settings**.

## Accessing Developer Settings

From your instance, go to **Advanced → Developer Settings**.

## Settings

### Debug Mode

Enables `WP_DEBUG`, causing WordPress to display PHP errors and warnings directly in the browser when you visit the site.

<Warning>
  Never enable Debug Mode on a live production site. Error output can expose sensitive configuration details to visitors. Use Debug Mode on staging environments only.
</Warning>

### Maintenance Mode

Displays a temporary maintenance notice to all visitors while you work on the site. The site remains fully accessible to you while maintenance mode is active.

Use this when making significant changes that may temporarily break the site's appearance or functionality.

### PHPMyAdmin

Provides direct SSO access to PHPMyAdmin for managing your site's MySQL database — browsing tables, running queries, importing and exporting data.

Click **Log In to PHPMyAdmin** to open it. PHPMyAdmin is also accessible from **My Hosting → MySQL Databases**.

<Info>
  PHPMyAdmin is intended for advanced users. Incorrect changes to the database can break your WordPress site. Always create a backup before making database changes.
</Info>

### PHP Version

Displays the current PHP version for the domain (e.g. PHP 8.3) and allows you to change it.

Click **Manage** to select a different PHP 8.x version. Note that PHP version changes apply to **all instances on the same domain**, not just the current one.

WP Cloud supports PHP 8.x only. PHP 7.x and earlier are not available.
