Difficulty requesting the Access Token With OAuth? Error: No token or token_secret

I'm hoping someone might be able to answer. I've been working on this for many hours and can't find the solution. I've also studied the HTTP_OAUTH documentation over and over as well as some tutorials. I'm stuck using that because my host doesn't support normal OAuth. That aside, it's not so bad. This is what I have so far. I'm able to:

1. Acquire an access token (URL_PATH_GOES_HERE?oauth_token=XXXXXXXXXXXXX)
2. Redirect the user to get their permission
3. Redirect back to my callback URL with an access token and oauth_verifier(URL_PATH_GOES_HERE?oauth_token=XXXXXXXXXXXXX?oauth_verifier=XXXXXXXXXX)

When I get there, however, I'm having difficulty requesting the Access Token so I can from there on out make requests on behalf of the user.

I keep getting the error:

No token or token_secret

Any ideas? I'd be eternally grateful!!

On your index.php file:

$_SESSION['request_token']        = $consumer->getToken();
$_SESSION['request_token_secret'] = $consumer->getTokenSecret();

On the callback.php file:

$consumer = new HTTP_OAuth_Consumer(OAUTH_CONSUMER_KEY, OAUTH_CONSUMER_SECRET, $_SESSION['request_token'], $_SESSION['request_token_secret']);
$consumer->getAccessToken(OAUTH_ACCESS_TOKEN_API,$_SESSION['oauth_verifier'],array(),'GET');
# and save the new tokens after
$_SESSION['request_token']        = $consumer->getToken();
$_SESSION['request_token_secret'] = $consumer->getTokenSecret();

I simply changed the callback.php file a bit to match the example and now it seemed to work. Do let me know if it works for you but for me I am getting back the correct response.

<?php

// START A SESSION SO WE CAN ACCESS VARIABLES SHARED WITH US BY INDEX.PHP
session_start();

// IMPORT CONFIGURATION FLE
require_once("misoconfig.php");

// IMPORT EXTERNAL CLASSES
require_once("HTTP/OAuth/Consumer.php");

 // Store these tokens (at least for now)
    $_SESSION['oauth_verifier']   = $_GET['oauth_verifier'];

try {
    // !!!CHANGED ARGUMENTS TO MATCH EXAMPLE
    $consumer = new HTTP_OAuth_Consumer(OAUTH_CONSUMER_KEY, OAUTH_CONSUMER_SECRET, $_SESSION['request_token'], $_SESSION['oauth_verifier']);
    $consumer->getAccessToken(OAUTH_ACCESS_TOKEN_API, $_SESSION['oauth_verifier'],array(),'POST');
}catch (Exception $e) {
    echo 'Access Token Exception: ',  $e->getMessage(), "\n";
}

?>

By the way, I know it's a lot of work but can you create a github repo for the sample after it works. I would like to be able to link to the example for other user's future reference. If not that's fine.
