Answer 1

Well, i found the solution in this site: https://wordpress.org/support/topic/visual-composer-is-not-working

first: edit html2element:.... in in /wp-content/plugins/js_composer/assets/js/backend/composer-view.js

html2element: function(html) {
        var $template, attributes = {},
            template = html;
        $template = $(template(this.model.toJSON()).trim()), _.each($template.get(0).attributes, function(attr) {
            attributes[attr.name] = attr.value
        }), this.$el.attr(attributes).html($template.html()), this.setContent(), this.renderContent()},

second: However if you open up the frontend editor you'll have this "trim" issue on custom_views.js:101 , and line 467 of another file. I forgot the name, but I think it may be frontend_editor.js.

edit in: \wp-content\plugins\js_composer\assets\js\frontend_editor\

• frontend_editor.js
• custom_views.js

Bad code:

this.$controls = $( _.template( template, data, _.extend( {},
            vc.template_options,
            { evaluate: /\{#([\s\S]+?)#}/g } ) ).trim() ).addClass( 'vc_controls' );

Fixed code:

this.$controls = $( _.template( template, data, _.extend( {},
            vc.template_options,
            { evaluate: /\{#([\s\S]+?)#}/g } ) )().trim() ).addClass( 'vc_controls' );

third: See the black magic.
