Sorry you are having trouble with the theme. The content is located in Page sections custom post type. I hope you have imported the sample data as explained the following video –
I urge you to watch the video and setup the site accordingly, if you have not already done so already, and then go through the very first section of the documentation named “Installation and Single Page Site Configuration” fully. It has several screenshots as well to help illustrate how to configure this theme. Once you do the same pls contact us for any help you require. Thanks.
