[Resolved] translated product category shows 404 not found

For info: I believe when the back-end URL's are the right ones, we set up in the wpml, than all should be good.

After that I use the following code to make things work on the front-end. This is how we did it with watervision. So the problem is the MISMATCH in the settings and what you actually see in the back-end when viewing the overview of product categories. There is a wrong slug for the languages.

function devvn_product_category_base_same_shop_base( $flash = false ){
if(defined('ICL_LANGUAGE_CODE')){
global $sitepress;
$languages = icl_get_languages('skip_missing=0&orderby=code');
if($languages && !empty($languages)){
$original_lang = ICL_LANGUAGE_CODE;
foreach($languages as $key=>$lang) {
$new_lang = $key;
$sitepress->switch_lang($new_lang);
$terms = get_terms(array(
'taxonomy' => 'product_cat',
'post_type' => 'product',
'hide_empty' => false,
));
if ($terms && !is_wp_error($terms)) {
$siteurl = apply_filters( 'wpml_home_url', get_home_url('/'));
$siteurl = ($sitepress->get_default_language() == $key) ? $siteurl.'/' : $siteurl;
foreach ($terms as $term) {
$term_slug = $term->slug;
$baseterm = str_replace($siteurl, '', get_term_link($term->term_id, 'product_cat'));
add_rewrite_rule($baseterm . '?$', 'index.php?product_cat=' . $term_slug, 'top');
add_rewrite_rule($baseterm . 'page/([0-9]{1,})/?$', 'index.php?product_cat=' . $term_slug . '&paged=$matches[1]', 'top');
add_rewrite_rule($baseterm . '(?:feed/)?(feed|rdf|rss|rss2|atom)/?$', 'index.php?product_cat=' . $term_slug . '&feed=$matches[1]', 'top');
}

$sitepress->switch_lang($original_lang);
