Turn the [acf] Shortcode Back On

Re-enables Advanced Custom Fields' own [acf field="..."] shortcode, which ACF 6.3 switched off by default for security.

add_action( 'acf/init', function () {
    if ( function_exists( 'acf_update_setting' ) ) {
        acf_update_setting( 'enable_shortcode', true );
    }
} );

Notes

Only turn this on if you trust everyone who can write content, since the shortcode can read any field of any post.
