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?

HELP!!!
