Wpbakery (Visual Composer) Does not work localhost

Question

I have a Wordpress site installation on my machine, which runs through Xampp.

I obtained a theme through themeforest site, and with it comes the plugin Wpbakery Page Builder. The big problem is that when I add an element to a page, it doesn’t show me the element in the administrative panel. At the front end he appears normal. Below image, I added an element(buttom) it only appears in front-end, in back-and the element only appears in the classic editor.

I was able to solve the error presented with a solution until simple, but I am publishing here to help someone with the same error.

Just update the PHP version to 7.0.x, in my case I used PHP Version 7.0.27

Everything working perfectly now.
