Thanks for using our theme and for contacting us.
Could you provide the URL of your site? I need to see how it looks like right now to be able to guide you.
Did you import “Grocery Market” demo content or another demo version?
If you have an empty WP installation, just watch this video https://youtu.be/4n1re0jKorc and install the desired demo. If you already have content on the site, let us know, do not do the full import of 2 demos at the same time.
