Hi

I’ve checked your site and found a js error in browse’r console: http://screencast.com/t/336nNWAZFp
Please make sure that you’re using V 3.1 of Newsmag theme, this version is available on themeforest, also try to deactivate all plugins except Visual Composer, deactivate the child theme, clear all caches, p[urge cdn files if your using then testy the site again.

Let us know how it goes.
Thanks!
