Displaying someone elses feed in web app



I have created a twitter app to add to a site for a client using all her info and for some odd reason it is displaying someone else’s twitter feed entirely ( no idea why.)
I ave refreshed the keys and they keep displaying the wrong tweets


A user timeline widget contains a widget ID associated with a specific account. Add a data-screen-name attribute with the username of the account you would like to display in place of the account associated with the widget or create a new widget.
