I’m not the admin 🙂 but the file is located inside your theme folder. Have you checked it yet?
Also, check out the Tutorials on the Epik forum page (first several sticky posts at the top). This tutorial specifically shows how to add the widget content on the homepage to look exactly like the demo – https://appfinite.com/topic/easy-way-to-setup-the-epik-homepage-in-one-click/
WordPress by default can only upload XML data like Posts, Pages, Menus, etc….but it won’t upload the Widget content on the homepage of the Epik theme, so you can use that plugin to automatically add them in if you want to.
Be sure to take a look at all the other tutorials as well.
