sorry, the conde change needed to be at line 42 of the WA_Universal_Email/MailFormatting_PHP.php file, and line 327 of the
WA_ValidationToolkit/WAVT_Scripts_PHP.php file. the change needed to be:
$domArr = split("\.",$domainName);
to:
$domArr = explode(".",$domainName);
i fixed it in both files for you.
