Hello,
Thank you very much for choosing our theme and for contacting us.
You have not activated the plugins in Appearance > Install plugins. It is an essential step in the installation process. Now you need to launch the Woocoommerce Wizard, however, I do not see in your Dashboard, I have checked and see that PHP max input vars is 1000, it should be 5000 min.
Please contact your host support, ask them to ensure the requirements provided here: https://xtemos.com/documentation/basel/ and then launch the Woocoomerce wizard, finally, you can install the base demo and then demo you wish.
If you have any questions or difficulties, please contact us.
Best Regards
