    Hi,

    When I go inside (/wp/wp-admin/edit.php?post_type=acf-field-group), I got the following error :

    Trying to get property ‘object_id’ of non-object

    # wordpress-seo/src/integrations/admin/admin-columns-cache-integration.php:112

foreach ( $indexables as $indexable ) {
    $this->indexable_cache[ $indexable->object_id ] = $indexable;
}

    $indexables returns an array of two empty items.

    A temporary fix :

    foreach ( $indexables as $indexable ) {
    if (empty($indexable)) continue;
    $this->indexable_cache[ $indexable->object_id ] = $indexable;
}

    Another fix I found is to rollback to 19.10 or less, then go back to 20.0.

    However, I don’t know if these “hotfixs” has other repercussions…

    Website infos :

    • WordPress 6.1.1
    • Yoast SEO 20.0 / 20.1-RC-7
    • PHP 7.4

    Thank you

    @striffly I just encountered this issue myself. There is something wrong with the indexables table of Yoast and you can fix it by installing the Yoast Test Helper plugin.

    You can read some more on this here: https://yoast.com/help/how-to-reset-yoast-indexables/

    This is not a solid solution for the underlying issue of the messed up indexables table but at least it can help you move on while Yoast is working on this issue.
