Visual Composer is 3rd party premium plugin bundled with the theme for free. It is being sold on CodeCanyon, which is Envato’s website. If you buy the plugin from CodeCanyon, you get the purchase code with it. Unlike if you buy a product from Creative Market and/or Mojo Themes/Mojo Marketplace.
You are right, the shortcode generator stopped working in FIrefox (even if I check the most recent version 30 of the browser). I will have a look at the issue and release the WebMan Amplifier plugin update ASAP.
Yes, this shortcode generator is simplified. There is no need for advanced shortcode generator as it was case with !LesPaul as you can use Visual Composer with the theme.
I can see the issue is related to Firefox globally. Thanks for the info.
This might explain German words but WordPress really shouldn’t pick up translations like this…
