Twitter recently retired it’s APi and the main focus of the latest version is to ensure that Twitter will remain functioning with the music theme.
What Changed in Twitter
Previously it was possible to retrieve Tweets for a Twitter Account anonymously. Twitter changed that and you now need a developer account to retrieve your tweets from Twitter.
What is the implications for me?
All that’s needed additional to your Twitter username is a registration at twitter itself to get secret keys and access tokens. This will take about 5 minutes. After the registration you can add the keys to your twitter username in the theme options panel, and your tweets will work as always.
Take a look at the video below for the twitter registration process.
