Board Thread:Support Requests - Getting Technical/@comment-26226346-20150410144328

So I followed the instructions on this wiki, and I got the following code from twitter:

Tweets by @TwitterName !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+"://platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");

So I uploaded this to mediawiki, and used  TwitterWidget on the home page (in source mode) and now all it says is Tweets by @TwitterName

Help please? Thanks
