Problem:
The client is experiencing an issue with the WPML SEO plugin where the Yoast SEO sitemaps are showing hreflang tags for hidden or disabled languages (ES, FR) even though these languages are not currently active on their website.

Solution:
We recommend modifying the plugin's codebase as a temporary workaround:
1. Open the file

/plugins/wp-seo-multilingual/classes/Shared/Sitemap/BaseAlternateLangHooks.php

.
2. Locate the

addAlternateLangData

function around line 59.
3. After the line

list( $elements, $getPermalink, $isIndexable ) = $this->getEntryHelpers( $type, $obj );

, insert the following code:

// Exclude hidden language posts
global $sitepress;
$hidden_languages = $sitepress->get_setting( 'hidden_languages', [] );

if ( $elements && !empty($hidden_languages) ) {
	foreach ( $elements as $lang => $element ) {
		if ( in_array( $lang, $hidden_languages ) ) {
			unset( $elements[$lang] );
		}
	}
}

This code will exclude posts in hidden languages from appearing in the sitemap's alternate language data.
