I also had the same problem… after some digging, it looks like the problem is in /wp-content/themes/enfold/config-templatebuilder/avia-template-builder/assets/js/avia-media.js, line 26:

$.AviaElementBehavior.wp_media = $.AviaElementBehavior.wp_media || [];

	$.AviaElementBehavior.wp_media_advanced =  function()
	{
		var $body = $("body"), file_frame = [], media = wp.media,

The problem is that ‘wp’ is not defined in media = wp.media.

I changed the last line as follows:

var $body = $("body"), file_frame = [], media = $.AviaElementBehavior.wp_media, // wp.media,

Now everything works fine… I did not contact the Enfold team yet on the issue.
Hope that helps,
Yoel
