Visual composer 4.7.4

Hi to all,

I have an old web site (creation on 2015), with Visual Composer 4.7.4, and before I re-created (update theme and visual composer as well), I need a quick fix in order to add content right now for the season.

So, the problem is when I am on Backend Editor, I get JS error

TypeError: a is null load-scripts.php:2:12412
    jQuery 7
    changeShortcodeParams http://www.thelavishcomfort.com/wp-content/plugins/js_composer/assets/js/backend/composer-custom-views.js?ver=4.7.4:870

    fetch Backbone
    show http://www.thelavishcomfort.com/wp-content/plugins/js_composer/assets/js/backend/composer-view.js?ver=4.7.4:846

as a result, I can’t see all rows, for example, a map.

This caused after the hosting changed to PHP7.1.

Could you suggest a quick fix for right now?

Please advise!
