So I got my Twitter feed working in WordPress but it isn’t very reliable and I don’t know why. So when I say this I mean when you refresh the page the tweet won’t show up any more. I’m not sure if my code is wrong or not.
It’s something in the jquery library itself that is erroring, which is super weird if you ask me. And you can see below that that part of your tweet is making it in. I’m afraid I don’t know what to tell you. I’d maybe try linking to the Google-hosted copy of jQuery.
