Never mind all, I figured it out.
I found out what the problem is. With the new version of the Tweet Blender and Twitters API. You need to setup your account information into the plugin. Navigate to Setting -> Tweet Blender -> Status. From there I’m sure you’ll see red text indicating you’ll need to set up your account and authorization. Once I did this, the widget was sticking to the sidebar again. picard-facepalm.jpg
I just wanted to post to say thanks so much for this. Just started using WordPress and this problem was driving me nuts! When in doubt… look in Settings.
