Hi,
To avoid missing the translation add the code below to your functions.php
function my_child_theme_setup() {
load_child_theme_textdomain( 'swiftframework', get_stylesheet_directory() . '/languages' );
load_child_theme_textdomain( 'woocommerce', get_stylesheet_directory() . '/languages' );
}
add_action( 'after_setup_theme', 'my_child_theme_setup' );
Create a directory called languages inside the child theme and copy your translate files to that directory.
Hope it helps.
