WP-Config Generator

The WP-Config Generator builds a complete wp-config.php with database settings, fresh security salts, debugging, hardening and memory limits. Nothing you enter, including the database password, leaves the page.

Step by step

1. Enter the database name, user, password and host your hosting panel gave you. Keep the table prefix as wp_ unless you have a reason to change it.
2. On the Security tab, choose the file-editing, HTTPS and core update rules to apply.
3. On the Debugging tab, set the environment type. Turn on debug mode only while you are tracking down a problem.
4. Adjust memory limits and revisions on the Performance tab, or clear a field to leave that constant out.
5. Download the file and upload it to the folder that holds wp-settings.php, or one level above it.

Example

A production site with the file editor disabled, HTTPS forced for the dashboard and revisions capped at 10 gets these lines, among others:

define( 'DB_NAME', 'acme_wp' );
define( 'DB_HOST', 'localhost' );
define( 'WP_ENVIRONMENT_TYPE', 'production' );
define( 'WP_DEBUG', false );
define( 'DISALLOW_FILE_EDIT', true );
define( 'FORCE_SSL_ADMIN', true );
define( 'WP_AUTO_UPDATE_CORE', 'minor' );
define( 'WP_MEMORY_LIMIT', '128M' );
define( 'WP_POST_REVISIONS', 10 );

Before you upload

• DB_HOST is not always localhost. Managed hosts often use a hostname, a port such as 127.0.0.1:3307 or a socket path.
• DISALLOW_FILE_MODS also blocks every update from the dashboard, including security updates. Use it only when deployments or WP-CLI handle updates.
• FORCE_SSL_ADMIN on a site without a working certificate locks you out of the dashboard until you edit the file again.
• Changing the table prefix on an existing site does not rename the tables.
