Uncaught Error: Call to undefined function ctype_alnum()

To avoid: “Uncaught Error: Call to undefined function ctype_alnum() in /wp-content/plugins/tarteaucitronjs/tarteaucitron.php:30” if PHP module is not enabled without breaking your website, you can add a “function_exists(‘ctype_alnum’)” before the 3 “ctype_alnum()” function usage, like this from line 29:

case “uuid”:
if (function_exists(‘ctype_alnum’) && ctype_alnum($data) && strlen($data) == 40) {
return $data;
}
break;
case “token”:
if (function_exists(‘ctype_alnum’) && ctype_alnum(str_replace(‘-‘, ”, $data)) && strlen($data) == 122) {
return $data;
}
break;
case “alnum”:
if (function_exists(‘ctype_alnum’) && ctype_alnum($data)) {
return $data;
}
break;
