here’s how i got it working:
set up a new app for this client/site and then get the keys
// Your Twitter App Consumer Key
private $consumer_key = ‘XXXXXXXXXX’;
// Your Twitter App Consumer Secret
private $consumer_secret = 'XXXXXXXXXX';
// Your Twitter App Access Token
private $user_token = 'XXXXXXXXXX';
// Your Twitter App Access Token Secret
private $user_secret = 'XXXXXXXXXX';
i used the tweet.js mod here: https://github.com/StanScates/Tweet.js-Mod
drop your tokens into the index.php inside the /twitter/ folder.
** you’ll need to update the modpath to reflect where the feed is being shown **
it’s a little fiddly, but it works.
good luck!
