License activation of Visual Composer

Hi, @davoudbagheri

For these, they mean that you should add the license keys or purchase the plugins to get your own keys.
It does not affect your site, don't worry. The key is just able to apply for only one domain and we used it for the demo site already. So if there is any update, we will update for the demo site then our customers can update for their site later.
In case if you want to get an update automatically, you can purchase the key on your own. So one more time, don't worry about this. Just dismiss the warning then continue your work.

Yame
