Generated form displayed as html code

[sigmundfridge]

Hi,

I think this may have been alluded to in a few other posts, but as I'm
a bit of a novice I wasn't sure.
I have followed the instructions as detailed on the site but when I go
to the address of the form I get this initial chunk of code followed
by the rest of the form code. It does something right if I open the
form in Dreamweaver (i.e. it displays the thanks page, with all the
correct formatting).

<?php
include_once("../configuration.php");
include_once("../wff_misc.php");
include_once("../objects/class.phpmailer.php");
if (sizeof($_POST) > 0 || sizeof($_FILES) > 0)
{
if ($GLOBALS['configuration']['email_

The full page can be found here...

I've tried making a few changes suggested (downloading
class.phpmailer.php file and changing to ../objects/wff_misc.php) but
still it just displays the code. Any ideas what's happening?

I've also noticed that if I try and open it with IE (above is opened
with Firefox) then it asks if I want to open a php file. If I do it
send me to Dreamweaver.

Thanks for any help
