“PHP Fatal error” when starting scan

Thanks for the update. But now I’m seeing a fatal error in my debug log when I start a scan. I’m also seeing a deprecation warning.

WordPress Version: 6.8.1
PHP Version: 8.3.22

20-Jun-2025 12:48:10 UTC] PHP Deprecated:  mb_convert_encoding(): Handling HTML entities via mbstring is deprecated; use htmlspecialchars, htmlentities, or mb_encode_numericentity/mb_decode_numericentity instead in /wp-content/plugins/wp-ada-compliance-check-basic/res/content_validation.php on line 38
