This article shows you how to fix TypeError: $ is not a function on line 1 (or any line) in Oxygen Builder.

Luckily this is a really simple fix, and it's caused by WordPress itself.

Whenever you add any jQuery code to Oxygen (via the JS section of a Code Block), this error will trigger because WordPress does not recognize jQuery well. Despite that issue, it does support jQuery, and it comes pre installed on the CMS. All you need to do is make it easy for WP to understand that you do, infact, want to use jQuery code on you Oxygen Builder Code Blog.

Here’s how to fix it. On a simple chunk of jQuery code, simply swap the $ for jQuery. Here’s an example:

Original: $('.my-paroller').paroller();

Oxygen Builder Compatible: jQuery('.my-paroller').paroller();

For longer jQuery in an Oxygen Builder Code Block that’s toggling the “TypeError: $ is not a function” error, use this:

(function($) {YOUR CODE})( jQuery );

That should solve your problem.
