Theme was installed with the given documentation. Tried it in many ways, but this theme doesn't work.
We are missing all of the elements for this theme in Visual Composer to work with the theme. The elements are shown in source code and can't be really edited. Also we can't edit the Header with Customizer or Prohost Options..
Support can't really help and doesn't answer anymore..
I cannot recommend this theme, this was a waste of money...
