[Resolved] Media Translation and Houzez theme: edit alt text for "property images"

Problem:
Unable to translate the alt text for 'property images' from English to German using the Media Translation feature in WPML. Despite changing the alt text in the Media Translation and Real Estate sections, the frontend displays the English alt text instead of the German alt text, and the backend reverts to the English alt text after saving.
Solution:
This issue is due to a compatibility problem with the Houzez theme. We have implemented a workaround by adding the following code to the functions.php file of your theme:

add_filter('get_post_metadata', 'wpml_compsupp7300_filter_fave_property_images', 10, 4);
 
function wpml_compsupp7300_filter_fave_property_images($null, $object_id, $meta_key, $single) {
     
    // Target the specific meta key
    if ($meta_key !== 'fave_property_images') {
        return $null;
    }
 
    // Prevent recursion by temporarily removing the filter
    remove_filter('get_post_metadata', 'wpml_compsupp7300_filter_fave_property_images', 10);
 
    // Fetch the original meta value
    $images = get_post_meta($object_id, $meta_key, $single);
 
    // Re-add the filter
    add_filter('get_post_metadata', 'wpml_compsupp7300_filter_fave_property_images', 10, 4);
 
    // Check if we actually got an array
    if (is_array($images)) {
        foreach ($images as &$image_id) {
            // Apply the WPML filter to each item (image ID)
            $image_id = apply_filters('wpml_object_id', $image_id, 'attachment', true);
        }
    }
 
    return $images;
}
