<?php
error_reporting(E_ALL);
ini_set('display_errrors','on');
?>
in the server validations behavior, set the failed redirect to the same page, but add a URL variable:
$WAFV_Redirect = "get-in-touch.php?failed=true";
this way if ht eURL variable is present we know if the issue is validation or email settings.
aslo, add the following code at the end of the page just be fore the closing </html> tag:
<?php @session_start(); var_dump($_SESSION); ?>
include a link to your page after making the changes.
