//Start the session $session = session_id(); if($session == "") { session_start(); }
 
That should just be session_start(); on its own. Make sure its at the top of the file as well so that headers haven't been sent.
 

//Start the session session_start(); if(isset($_SESSION['lastMailed'])) { if($_SESSION['lastMailed'] + 60 < time()) { $response['error']['time'] = 'Whoah, slow down there! Please wait 60 seconds before sending another enquiry'; } }

The second line is:
 
header("Cache-control: private");
 
and fixes a bug in IE in certain situations on Windows XP.

Not 100% convinced this will work but try it anyway...
 

var messageList = $('<ul />'); $.each(response.error, function(index, value) { $('<li/>').html(value).appendTo(messageList); }); $('#message').append(messageList);

simple way would to have a file using the define function to define some constants
 
config.inc.php

<?php define('DB_HOST', 'localhost'); define('DB_USER', 'username'); define('DB_PASS', 'password'); define('DB_DATABASE', 'database name');
 
and then to use it just use
 

<?php require_once 'config.inc.php'; // say the file is in the web root... save the config file to the directory outside // so no one can view it directly and use this line instead // require_once dirname(dirname(__FILE__)).'/config.inc.php'; $connection=mysql_connect (DB_HOST, DB_USER, DB_PASS); mysql_select_db(DB_DATABASE, $connection);
 
 
i dont use ?> to end php at the end... you dont actually have to if its just php and saves on errors with sending header data due to a random new line character at the end of the file

I've just had a quick play around with your css try this
