As per the nature of this kind of problem, I can't fix it for you, but I can give you a list of things to verify that are very likely to be where the problem comes from.

• Possible scenario is that a script tag contains calls to jQuery before the application.js file is loaded. Check in your HTML (including template) where is located the loading application.js, and verify is any call to $ is done before it
• Another scenario is that you are loading several manifest and another manifest is calling to jQuery and is also loaded before application.js. Check on this in your HTML files.
