I found that I can set PHP to 4.4.2-pl1 with Xampp. That didn't help. I
tried putting in a space, that didn't help either.

I am not sure exactly how to do this. I had:
header("Location: $HTTP_REFER");
Do I keep the quotes? Do I keep the "Location:" ? It doesn't seem to
work either way.
I tried it like this:
header($_SERVER['HTTP_REFERER']);
And got these errors:
Warning: Cannot modify header information - headers already sent by
(output started at C:\xampp\htdocs\WMS\authenticate.php:2) in
C:\xampp\htdocs\WMS\authenticate.php on line 5
I also don't understand why this works perfectly on my web-site. Also,
I don't understand why I'm not getting my $username and $password
strings.
This is from by index.html file:
<form action="authenticate.php" method="post">
Username:<br>
<input type="text" name="username">
<br><br>
Password:<br>
<input type="password" name="password">
<br><br>
<input type="submit" name="Log In">
</form>
This is the authenticate.php file:
<?php
#if either form field is empty return to the log-in page
if ( (!$username) or (!$password) )
{
header($_SERVER['HTTP_REFERER']);
exit();
}
The $username and $password strings seem to be empty. I tested them.
