I'm using the BigSlide.js sliding menu on my drupal site, which i've built into the theme, and it works fine on every page, apart from on /edit/ pages. E.g. user/%/edit.
When clicking the target menu button nothing happens - the menu should slide out from the left.
In the chrome console i'm getting:
Uncaught TypeError: undefined is not a function
As you can see from the image above it's referencing bigSlide.js, I've tried updating jQuery to 1.9 with the Jquery update module as i'm using 1.7 and that didn't help, and i've made sure all my JS files are being loaded on /edit/ pages.
What could be the problem?
Here's the issue spot within bigSlide.js
Any help much appreciated.
