Hey Papermouse,
A fellow user here who has experienced and resolved the same issue, and felt I would jump in as support might not catch this until Monday.
The change came in woocommerce 2.5 and is not theme related.
We added this script to our child theme functions.php file and it worked a treat:
function wc_ninja_remove_password_strength() {
if ( wp_script_is( ‘wc-password-strength-meter’, ‘enqueued’ ) ) {
wp_dequeue_script( ‘wc-password-strength-meter’ );
}
}
add_action( ‘wp_print_scripts’, ‘wc_ninja_remove_password_strength’, 100 );
