Uncaught ReferenceError: $ is not defined

My site: http://www.relishdecor.com



Today, I just started getting javascript errors preventing certain actions from rendering on the front end (homepage banners, quick view, tabs on a product page, etc.).



Example error messages from my Inspect Element console:


<br />
Uncaught ReferenceError: $ is not defined<br />
Uncaught ReferenceError: lang is not defined<br />
Uncaught ReferenceError: jQuery is not defined
```<br />
<br />
In the admin area, I can't modify blocks or navigate through tabs of the products for example.<br />
<br />
I recently added SSL to my server but do not think this is related. The paths to the supporting js files have not changed and are still correct.<br />
<br />
Has anyone else run into this?<p><a href="127.0.0.1/uploads/monthly_04_2013/post-21105-0-41276100-1366594823.png">Screen Shot 2013-04-20 at 3.02.20 PM.png</a></p>

Can only assume you are missing brackets around a $lang template variable or that you are not using “literal” tags where needed.
