Now I get it. Must be the version change?

Any idea why this bit of code

if("yes" == $_POST['submitter'])

is provoking this message in my Apache error log?

Because $_POST['submitter'] is not set?

Because your script assumes it IS set?

Because sometimes your script is called to display the form, before
$_POST['submitter'] has anything in it, and sometimes it's called
after they hit submit and it has something in it?

if (isset($_POST['submitter']) && "yes" == $_POST['submitter']){
