 * Hi!
 * I started getting an error after PHP 8 update (thought it might not be related).
 * The error report is sent automatically by wordpress plugin errors autodetection
   feature. It reports that error occurred on this page: /wp-admin/plugins.php?plugin_status
   =all&paged=1&s
 * WordPress 5.8.1
    Theme: Zakra (2.0.5) User Menus: 1.2.7 PHP: 8.0.11
 * From time to time I get the following report sent to admin email:
 *     ```
       Uncaught ValueError: Unknown format specifier "Ð" in /var/www/html/wp-content/plugins/user-menus/freemius/templates/forms/deactivation/retry-skip.php:23

 * Digged a little more and looks like the string that comes to sprintf has UTF8
   characters in it. And sprintf does not support utf8, thus fails.

 * Hello [@dhampik](https://wordpress.org/support/users/dhampik/),
 * Thanks so much for your patience.
 * It looks like we’ll need to update the Freemius library. See below.
 * [https://github.com/Freemius/wordpress-sdk/issues/510](https://github.com/Freemius/wordpress-sdk/issues/510)
 * I’ll create an issue for this on our GH repo.
 * Thanks again for reporting this to us!
 * Have a great day 🙂
