I purchased the simple theme (http://demo.whoathemes.com/simple/). Installation works without. I installed all plugins except the following two: WPBakery Js Visual Composer.
Wordpress suggests they are mandatory but I cannot find them in the theme bundle. It seems I cannot downoad them online either. Instead I see them for sale on Envato. I hope I don’t have to buy them separately. I would expect any theme I buy to include any mandatory plugin. No?
Thanks for your input. I must be missing something obvious.
