Thank you for reporting this to us!
I’ve checked the error, and it is actually originating from the translation-stats plugin. In PHP 8.1+, a “Deprecated” warning is thrown if a null value is passed to certain functions, which seems to be happening within their class-locales.php file.
Please be assured that our plugin, Bousaid AI Slug Generator, follows the standard WordPress translation structure and does not contain any faulty translation files that would cause this.
Since this is merely a Deprecated notice, it won’t affect your site’s functionality. We recommend hiding these notices on your live site by setting WP_DEBUG_DISPLAY to false in your wp-config.php file. You might also want to let the authors of the Translation Stats plugin know about this so they can patch it.
Best regards,
