Rank Math SEO adds incorrect sitemap entries for translated homepages

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.

There is a known issue like this before with the WPML platform and they released a workaround for this. Could you please try downloading this plugin and let us know if the issue still persists?

I hope that helps.

Thank you.

Hello,

In this case, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.

Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.

Thank you.

Hello,

We fixed the issue on your website by adding the following filter:

if ( 'page' === get_option( 'show_on_front' ) ) {
    add_filter( 'rank_math/sitemap/entry', 'compsupp_5514_filter_sitemap_home_page_entry', 10, 3 );
}
function compsupp_5514_filter_sitemap_home_page_entry( $url, $type, $post ) {
    global $sitepress;
    static $wpml_home_urls = null;
    static $frontpage_translations = null;
    static $default_frontpage_id = null;
    if ( ! $wpml_home_urls ) {
        $active_languages = $sitepress->get_active_languages();
        $wpml_home_urls   = [];
        foreach ( $active_languages as $code => $language ) {
            $wpml_home_urls[ $code ] = $sitepress->language_url( $code );
        }
        $default_frontpage_id   = get_option( 'page_on_front' );
        $frontpage_trid         = $sitepress->get_element_trid( $default_frontpage_id, 'post_page' );
        $frontpage_translations = array_map( \WPML\FP\Obj::prop( 'element_id' ), $sitepress->get_element_translations( $frontpage_trid, 'post_page' ) );
    }
    if ( in_array( $post->ID, $frontpage_translations ) && $post->ID !== $default_frontpage_id  ) {
        $language_code = array_search( $post->ID, $frontpage_translations );
        $url['loc']    = $wpml_home_urls[ $language_code ];
    }
    return $url;
}

This removes the extra word from the slug of your pages.

Don’t hesitate to get in touch if you have any other questions.
