Ok, I pretty much just Googled the RSS issue with Twitter and figured it out. Twitter changed their link to the RSS feed. You just need to change one line of code and the plugin will work fine.
Go to your plugins folder > news-bar > includes > get-news.php
Go to line #50, it should look like this:
$messages = fetch_rss( 'https://twitter.com/statuses/user_timeline/' . $username . '.rss' );
You want to change it to this:
$messages = fetch_rss( 'https://api.twitter.com/1/statuses/user_timeline.rss?screen_name=' . $username );
New Twitter link and remove the “.rss” at the end. Here is the link to the dev forum where I found this:
