PHP imagettfext not displaying working
I used to use a script to change the text on an image via update form.
It worked perfectly at first while I was on a shared host with all modules pre-installed.
I moved to a vps where I had to install everything myself and now the script no longer works.
The php page is able to be displayed but when I update, the text does not show up like it used to.
Here is an example of the page on the shared host that still works: http://nyanpuffle.com/auntarctic/ Password is 1234
Here is an example of the page on the vps that does not work: http://www.clubpenguincheatsy.com/cptrackers/auntarctic/ Password is 1234
Here is a copy of the coding used:

<?php
$submit = $_POST['submit']; // Gets If It has been Submitted
if($submit){ // If submitted do this.
$password = $_POST['password']; // Get the password they submitted
$status = $_POST['status']; // Get the status they submitted
$server = $_POST['server']; // Get the server they submitted
$room = $_POST['room']; // Get the room they submitted
//Now We Secure it.
if($password == "1234"){
//Now We Generate the image and stuff.
$im = imagecreatefrompng("in.png");
// Make RGB Colour For Writing
$colour = imagecolorallocate($im, 255, 255, 255); // I want mine in red(This is black). So I am just
//Gonna find out the rgb code
$font = 'BurbankBigRegular-Bold.ttf'; //
//This ^ Is our font, It has to be the exact name and in the right folder.
//Draw Text
imagettftext($im, 20, 0, 100, 68, $colour, $font, $status);
imagettftext($im, 20, 0, 95, 95, $colour, $font, $server);
imagettftext($im, 20, 0, 85, 127, $colour, $font, $room);
//Create Image
imagepng($im,'out.png');
// Destroy - Save Server Resources
imagedestroy($im);
echo "<b> Updated! </b>";
}else
{
echo "<p><b>Incorrect Password!</b></p>";
}
}
//This form remebers what they put, so they dont have to keep typing it in.
// $_SERVER['PHP_SELF'] Means Get this document to submit to.
// If you know html this will be familiar.

The VPS is ran on Ubuntu and I have PHP,MYSQL, and Apache installed.
Your original code throws Undefined variable: errors on all your variables, you should always set variables before using them, this includes $_POST variables, you should enable error reporting error_reporting(E_ALL) when developing and then change too error_reporting(0) when you upload to a live site then your see the errors that are stopping the processing/updating of the image.
Ive fixed your code with some changes:
<?php
header("Cache-Control: no-cache, must-revalidate"); //remind the browser not to cache the image
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
error_reporting(E_ALL); //Change to 0 when live
?>

Notice the htmlentities() & the non use of $_SERVER['PHP_SELF'] in the form.
EDIT: Taken from http://php.net/manual/en/function.imagettftext.php
The path to the TrueType font you wish to use.
Depending on which version of the GD library PHP is using, when fontfile does not begin with a leading / then .ttf will be appended to the filename and the library will attempt to search for that filename along a library-defined font path.
When using versions of the GD library lower than 2.0.18, a space character, rather than a semicolon, was used as the 'path separator' for different font files. Unintentional use of this feature will result in the warning message: Warning: Could not find/open font. For these affected versions, the only solution is moving the font to a path which does not contain spaces.
In many cases where a font resides in the same directory as the script using it the following trick will alleviate any include problems.
<?php
// Set the enviroment variable for GD
putenv('GDFONTPATH=' . realpath('.'));
// Name the font to be used (note the lack of the .ttf extension)
$font = 'BurbankBigRegular-Bold';
?>
$font = 'BurbankBigRegular-Bold.ttf';
replace with :
define ("_DOC_ROOT", dirname( __FILE__ ) ."/" );
$font = _DOC_ROOT.'dir_u_know/dir_u_know/BurbankBigRegular-Bold.ttf';
