Answer 1

If you are unable to solve this error by upgrading or downgrading your theme or plugin, you could at least make the below changes.

1. Open the following two files:

wp-content\plugins\js_composer\assets\js\frontend_editor\frontend_editor.js
wp-content\plugins\js_composer\assets\js\frontend_editor\custom_views.js

2. Replace

this.$controls = $( _.template( template, data, vc.template_options ).trim() ).addClass( 'vc_controls' );

with

this.$controls = $( ( "vc.template_options" ).trim() ).addClass( 'vc_controls' );

This will surely work.
