Hello,
If you use Massive Addons plugin it has compatibility issues with the new WP update – WPBakery Page builder (formerly Visual Composer) can’t work correctly. Either downgrade the WP to the previous version or wait for the Massive addons plugin update, when they release fix for this https://codecanyon.net/item/massive-addons-for-visual-composer/14429839/comments?page=109&filter=all#comment_24928281
