Twitter widget stopped working since they changed their API to 1.1 on June 12th, 2013

Unfortunately Twitter drastically changed their API with the release of version 1.1 and now there is authentication required (consumer and user private and public keys) for you to be able to display Twitter feed or your Twitter follower count in your theme. For our themes that support the follower count (GrandMag and Flavor) we were actually able to find a fix for that and are including it in the next update for each theme, respectively. For the actual Twitter feed in all of our themes, unfortunately for now we're going to have to remove that functionality in the next update to each theme until we can find an alternative solution. However, in the mean time, we recommend just using a plugin for your Twitter feed instead of the theme's built-in widget. Check out the plugin directory for lots of great options: http://wordpress.org/plugins/. Thanks for your patience and understanding during this new Twitter transitional time!
