Visual Composer Back-end editing issue

So Im trying to edit my site in Wordpress using the Visual Composer, all look fine when previewing it in a browser. But when I go in the Visualizer back-end mode; the elements seem to disappear and only show bits. Though when I click classic mode all the code is there. What could be the cause of this?


It’s better to contact the theme author for free support due to forum is for general purposes.
