"Could not authenticate you." -error when using Twitter OAuth

Question

I'm building my first system using Twitters OAuth and have some issues.

First, I'm using Abraham's Twitter-class for this and I have followed this tutorial. However, I get these lines on my callback.php:

Warning: array_merge() [function.array-merge]: Argument #2 is not an array in C:\xampp\htdocs\twitter\twitterOAuth\OAuth.php on line 301

Warning: strtoupper() expects parameter 1 to be string, array given in C:\xampp\htdocs\twitter\twitterOAuth\OAuth.php on line 373
Oops - an error has occurred.
SimpleXMLElement Object
(
    [request] => /account/verify_credentials.xml
    [error] => Could not authenticate you.
)

Is this problem by Twitter-class, or am I doing something wrong? I have my Consumer Key and Consumer Secret in config.php as tutorial says, but should I store something else?

Solution

The Snipe.net tutorial is for an older version of TwitterOAuth. Make sure you read the new documentation

http://github.com/abraham/twitteroauth/blob/master/DOCUMENTATION

In general updating to the new version is changing:

$content = $to->OAuthRequest('https://twitter.com/account/verify_credentials.xml', array(), 'GET');

to:

$content = $to->get('account/verify_credentials');
