Multiple timeline widget causes error message


I created timeline widgets through my Twitter account setting. It works fine if there is only one per page. When there are more than one, I get an error (below) in the console. Any idea why this is happening? Does it have anything to do with the application settings? I work with multiple websites, and sometimes a website needs multiple Twitter timeline feed widgets.
Any help is much appreciated!
