TypeError: $this.find(…).on is not a function Error

In your site jQuery core file version is 1.4 and in this version jQuery on() not defined so go to the ajaxify.js file and replace .on by .live.

I am sure this will solve your problem.

Suggestion: Always try to use latest version of jQuery

Thanks for your quick reply. I’ll try that right now!

How do I be sure to use the latest version of jQuery? Does this not update with wordpress?

Check in code source jquery.js file version.

Thanks for your help so far.

I temporarily fixed the problem but now it’s no longer working but I don’t see any errors either. I’m confused.

I think problem is with menu container details.

Can you take a look for me. If there’s a cost, let me know what that is.
