My visual composer isn’t working. I’m in Page edit mode, and I’m trying to add a visual composer element, but whenever I click on something, nothing happens. For example, if I click on SNS Custom Box, nothing happens. Same things happens for every visual composer element.

There is an update available for WPBakery visual composer, but when I click to download, it says I need to purchase it. Wasn’t visual composer included in this theme? It worked when I first downloaded it,
