    Hi,

    After updating to PHP 8.1 I got a Fatal Error:

    PHP Fatal error:  Uncaught ValueError: Unknown format specifier " " in /xxx/wp-content/plugins/wordpress-seo/admin/metabox/class-metabox.php:204
Stack trace:
#0 /xxx/wp-content/plugins/wordpress-seo/admin/metabox/class-metabox.php(204): sprintf('Az oldalra muta...', '<a href="https:...', '<span class="sc...')

#6 {main}
  thrown in /xxx/wp-content/plugins/wordpress-seo/admin/metabox/class-metabox.php on line 204

    Is Yoast compatible with PHP 8.1? If yes why I got this error and how can I solve it?

    Thanks.

    Hello @beamkiller,

    I’m sorry about the fatal error you encountered after updating to PHP 8.1. Is yours a multilingual site using WPML?

    Hi,

    Thanks for suggestion. There is no WPML.

    But based on this input I managed to find the error.

    There were wrong translations in Loco Translate where the variable string for PHP had spaces in it.

    For example: %1$s
    Was like this: % 1 $ s

    Thanks.
