I have a suspicion that it is a server problem... But can you guys detect a problem with this code that would cause it to randomly sometimes not load?

<?php
include("this_file.php");
$page_id = intval($_GET['pid']);
if (!$page_id){
$page_id = 1;
}
$page_details = mysql_fetch_assoc(mysql_query("SELECT * FROM `site_pages` WHERE `page_id`='$page_id'"));
$page_name = "www.x.co.za/index.php?pid=" . $page_id;
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>
<head>
<title><?php echo($page_details['page_title']); ?></title>
<link rel="stylesheet" href="default.css" type="text/css"/>
<link rel="stylesheet" href="drop-down.css" type="text/css"/>
</head>

<body>
<table width="800" align="center" cellspacing="0" cellpadding="0" style="background-color:white;">

<?php include("includes/header.php"); ?>

<tr><td colspan="2" class="c_blue" height="5"></td></tr>
<tr><td colspan="2" height="30" id="gray_bar">

I'm guessing you're getting a PHP error that is stopping the script.

In this part:

<?php
include("this_file.php");
$page_id = intval($_GET['pid']);
if (!$page_id){
$page_id = 1;
}
$page_details = mysql_fetch_assoc(mysql_query("SELECT * FROM `site_pages` WHERE `page_id`='$page_id'"));
$page_name = "www.x.co.za/index.php?pid=" . $page_id;
?>

Use the server PHP error log, and log PHP errors to see what's happening.

Maybe try something like this (thinking that $page_id is null, but it exists) ...
And what if $page_id=0 or $page_id=9999999?
Are there limits to what it can be?

<?php
include("this_file.php");
$page_id = intval($_GET['pid']);
if (strlen($page_id)<1){
$page_id = 1;
}
$page_details = mysql_fetch_assoc(mysql_query("SELECT * FROM `site_pages` WHERE `page_id`='$page_id'"));
$page_name = "www.x.co.za/index.php?pid=" . $page_id;
?>

Well even if $page_id is null it would just generate a notice. Of course I told him to use error_reporting(6143); but he obviously removed it at some stage.

Anyway the problem is, the page doesn't generate an error, just sometimes it doesnt load AT ALL, its really weird... just says the page cannot be found...

You can sit at two computers and open the website, it opens on one and not on the other. Then both, then none. But it just seems really random.

That is most likely a server or internet problem, if no PHP error is output.
