Our theme bundles the WPBakery Page Builder (formerly known as WPBakery Visual Composer) and as stated from it's developers: "Please note: If WPBakery Page Builder came integrated into your theme, then ask your theme provider to update WPBakery Page Builder for you" (source: https://kb.wpbakery.com/docs/getting-started/update/). For a newer version, you can get it from our ticksy article: https://highgrade.ticksy.com/article/12954/

The theme turned out to be a bit more complex than I had originally thought, but the customer support I received was absolutely incredible. Dragos Rada provided in-depth answers to my neverending questions and spend the time to really answer my questions thoroughly. I would highly recommend this theme mostly because of its customer support. I can say without a doubt that I never would have been able to build my website without the help of Dragos Rada!
