[Resolved] on the frontend the button shows only link of ENGlish

Problem:
The client has an issue where a button on the English version of their site, which should link to the German version, only shows the English URL.

Solution:
We recommend the following steps:
- Add the following code to the theme's functions.php file:

add_filter( 'wpml_sl_blacklist_requests', 'wpml_sl_blacklist_requests', 10, 2 );

function wpml_sl_blacklist_requests( $blacklist, $sitepress ) {
    $blacklist[] = 'downloads';

    return $blacklist;
}

Adjust the $blacklist array as per the slug(s) of your pages/posts.

- If the issue persists on the said page, it may be due to corrupted entries. We advise deleting the page (including from Trash) and recreating it, along with its translations.

For more information on linking to pages in a different language, please refer to our guide: Linking to pages in a different language.
Additionally, if you need to delete a translation of a page, follow this guide: How to delete the translation of a page.
