"The wp_nav_menu Function" WordPress Development Section---> Hamburger not working

I have followed Step by Step Directions and correctly executed everything . As of now when i click the hamburger icon the nav menu does not appear. After a couple hours i copy and pasted the downloaded file into my own, and that's not working either. The only thing showing in the console is this --->Uncaught ReferenceError: jquery is not defined at app.js:1, which has been consistent with the file i created and the file created by teamtreehouse.

jQuery is probably not loading. Try adding this before your enqueue scripts wp_enqueue_script('jquery');

hey mahammed, do i put it in function wpt_theme_js() at the top?

1 Answer

The code you posted is the same code that was given to you for this project? did you modify any portion of it? Just from a glance, I see that you are canceling out normalize.css and you are using foundation.js as a dependency in your app.js file. I would try and remove that first and just have jQuery as a dep, and then go from there.
