In your classic demo theme I could see few fields like the forum, articles and media tab which is absent in my website. How can I add them to my website too. Screen shots are attached for reference. I think the media tab could help me in adding more images of the user to create a image gallery.
You're trying to setup your theme but you're experiencing errors when importing the demo content? Or you've just followed the setup guide but your website doesn't look exactly like our demo? These are common issues for which you can find easy and quick fixes.
