Twitter Feed Not Working


I’m a self-taught developer and several years ago installed a Twitter widget the draws from in our company’s website. Recently the feed stopped working and I understand that it may have something to do with a deprecated link. I have done my best to learn what I can from the forum but I’m still not clear as to how I can fix the problem short of replacing the widget with an embedded timeline. Unfortunately, the embedded timeline is too large and will not fit in the space allocated on the web page. Could someone please provide me with help to get the widget working again? I’ll greatly appreciate any help.
