in the email behavior, you are using a full address for the include location:
include("http://www.safariawards.com/webassist/email/waue_nominators_insert_1.php");
this cant be a full lURL, it has to be a relative path.
also, for the redirect, you use a full URL:
$WA_redirectURL = "http://www.safariawards.com/nomination_thanks/";
again, this needs to be a relative path.
