installing twitter and oauth on drupal I have just been trying to get twitter going on my drupal 7.21 website.  i followed the tutorial at http://drupal.org/node/1346824 
Everything was fine until the last step of authorising a twitter account, when i got a blank page back from the twitter app and a message saying "unauthorised oauth request".  I've tried re-installing, messing with callback URL's etc but cannot get anything to work. Has anyone else solved this problem?
Thanks
Andy
After the new Twitter API upgrade, I would recommend using the Twitter Pull sandbox project. It works beautifully.
