Hello,
Thank you very much for choosing our theme and for contacting us.
Your screen and question is not clear enough. I see you have installed and activated the theme.
Have you installed all the plugins required for the theme? You need to do that. Appearance > Install plugins. Next, if you want you can upload the demo content. https://xtemos.com/docs/basel/installation-process-2/
If you need more help please provide more details.
Best Regards
