I tried the following solutions:

• maulik`s (but there was no such files on my plugin folder - frontend_editor.js and custom_views.js, just a "vendors" folder on "/wp-content/plugins/js_composer/assets/js/frontend_editor"),

• Amritosh pandey`s solution (does not work even after cache & history cleaning),

• Berein`s solution (does not work too).

I solved the problem by using a Amritoshpandey's solution: https://gist.github.com/levantoan/519bb0d42c9f7bd6c4d78ef1686bb848 ("The following code has completely corrected my problems, I can load the page, add, clone, remove, etc")

The Amritoshpandey's code should be pasted in /wp-content/plugins/js_composer/assets/js/dist/backend.min.js instead of:

render:function(){var $shortcode_template_el=$("#vc_shortcode-template-"+this.model.get("shortcode"));if($shortcode_template_el.is("script"))this.html2element(_.template($shortcode_template_el.html(),this.model.toJSON(),vc.templateOptions["default"]));else{var params=this.model.get("params");$.ajax({type:"POST",url:window.ajaxurl,data:{action:"wpb_get_element_backend_html",data_element:this.model.get("shortcode"),data_width:_.isUndefined(params.width)?"1/1":params.width,_vcnonce:window.vcAdminNonce},dataType:"html",context:this}).done(function(html){this.html2element(html)})}return this.model.view=this,this.$controls_buttons=this.$el.find(".vc_controls > :first"),this},
