Fixing HSTS with Code Snippets

I’m not super familiar with this issue, but this site seems to provide some solutions: https://thomasgriffin.com/enable-http-strict-transport-security-hsts-wordpress/

I always recommend using anonymous functions over named functions when writing snippets, so I’ve rewritten the code in that article slightly for you:

/**
 * Enables the HTTP Strict Transport Security (HSTS) header in WordPress.
 */
add_action( 'send_headers', function () {
	header( 'Strict-Transport-Security: max-age=10886400' );
} );

Let me know how that works out!

It looks like that worked, so thanks very much!
