Contact Forms used for years have stopped working_问答_开发者

I posted earlier, but have more information so would like to try again. I am trying to help a friend sort out a problem with the contact forms on his web page, which is built using SiteMan. He has a basic 'contact me' form and a 'request a quote' form on his page. The page is meadowwoodpedestals.com and it is hosted on BlueHost. These forms have worked for years, but we have just discovered that he is not receiving messages being sent via these forms. Upon testing, we found that when the submit button is clicked for either of these pages, instead of getting a confirmation screen, a blank screen is displayed and no message is sent. It has been months since he made any changes in the SiteMan editor.

(1) I contacted the host for support, and the reply told me that the errors indicated a problem with the page code for these two pages:

Premature end of script headers: 500.php, referer: http://www.meadowwoodpedestals.com/content/index.php?page=quote

Premature end of script headers: 500.php, referer: http://www.meadowwoodpedestals.com/content/index.php?page=contact

The response said: As you will see, it appears that the issue is with the code itself. You will need to have your web designer, or a script specialist, look over the code for the two pages, in order to resolve these issues. (My Note: the web designer is out of business)

(2) I found the following in the Bluehost forums (this is a bluehost site), I'm not sure if it is relevant?

"The premature end of script header, on a Bluehost server, is more than likely due to CPU quota (or memory?), the script was killed due to resource limitations."

(3) I looked at the page code for the contact form, which uses method="post" action="/cgi-bin/frmctact.php" and all of the basic html looked good - I don't know javascript so I am not sure about this (I've never seen that little cross symbol before?):

<script type="text/javascript" language="javascript">  
function m_sfcon (u) {  
pre = "mail";  
url = pre + "to:" + u;  
document.location.href = url + "@meadowwoodpedestals.com";  
}†</script>

(4) I looked at the page code for the quote form, which uses method="post" action="/cgi-bin/mail/mail.php", and there are no script tags at all on that page.

(5) Without posting reams of code (as I'm not sure just what is useful), here is my thinking, please let me know if this is a reasonable track:

Since there are two different pages with the same error, I'm thinking it is not really a problem in either quote.php or contact.php
The two forms use different actions, so I'm guessing it is not mail.php or frmctact.php
==> There must be something common between the two pages, but what is it?? maybe index.php?

(6) I looked at index.php, and when I clicked on the opening php tag it closed with a tag in the sixth line of this statement (the ?> just prior to 'si",):

$adress = "http://" . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']);

include("data/page_header.php");
switch ($do) {
case "prevphp":
    if ($Siteman->mlevel >= 4) {
        echo preg_replace("'<\?php.*?\?>'si","",stripslashes($_POST["content"]));
    }
    break 1;

case "default":
    if ($info[2] == 1 || $Siteman->mlevel >= $info[2]) {
        include_once($content);
        if ($Siteman->mlevel < 5) {
            if ($page == "index") {
                if (substr_count($_SERVER["HTTP_REFERER"],$adress) == 0) {
                    echo "<script language=\"Javascript\" type=\"text/javascript\">
                    var res = screen.width.toString() + 'x' + screen.height.toString();
                    var referer = '" . urlencode($_SERVER["HTTP_REFERER"]) . "';
                    document.write('<img width=\"1\" height=\"1\" src=\"stats.php?new=1&amp;res=' + res +      '&amp;referer=' + referer + '\" id=\"stat\" name=\"stat\" />');
                    </script>";
                }
            }
        }
    }
    break 1;
}
include("data/page_footer.php");

?>

(I don't know why this page works with address misspelled...)

Should I post the full code in cgi-bin/mail/mail.php and cgi-bin/frmctact.php to this area?

My sincere thanks for any / all help! Abby

EDIT - Here is full frmctact.php - I deleted some blank lines and repeated warnings

The 500 errors mean PHP is crashing. You need to look in the apache error log (bluehost have an icon for this in the cpanel, IIRC), and hopefully will see some PHP error message.
