Hi there,
When i install the theme and install all the plugin as required and active them all. Then install base demo content, after that I got problem when I go to front-end, just show white page. I find when I deactivate the WPBakery Visual Composer plugin, can show content in front-end but layout broken. If activate the WPBakery Visual Composer plugin, just white page show up.
The version of WPBakery Visual Composer is Version 4.9.2.
