Staging and Visual Composer/WP Bakery

Hi,

Our “live” website is janusview.com and we are creating a staging site (staging.janusview.com) where we can test upgrades before we push out to the live site. We had two questions related to this:

The kleo theme does not work on the staging site – it is primarily the visual composer/wp bakery plugins that do not work (and the  front page looks like garbage). I downloaded the latest version of kleo from envato and tried to use the plugins from there. However, the plugins k-element, visual composer keep saying that this is not the latest version, and I need the latest version for them. But I am not sure how I can get these: for security, we do manual installs by downloading plugins and amminstead of ftp into wordpress, and the visual composer site does not have an option to allow this.

Ques 1: Since both the staging and live site are sitting on the same machine and are for the same site, can we work with the same kleo license? Or are we needed to buy two licenses (which sounds a bit ridiculous)?

Ques 2: Why are the versions of the plugins provided in support of the latest theme not up-to-date with the theme version requirement?

Additionally, we had WP Bakery Builder (and it is difficult to tell where VC begins and WP Bakery ends) in the live version, but this plugin is not noticeable anywhere (so it is not clear how we get that). Please help.

Thanks
