Hello, Enderkadir,
We’ve imported demo content. Please check.
It is recommended to run import on a fresh WordPress installation.
For this, you can use the WordPress Database Reset plugin https://wordpress.org/plugins/wordpress-database-reset/
The plugin can be used to remove all the existing content and install a new version from scratch.
Also, we can see errors from WooCommerce on your site. Please check the Private Content area.
Kind Regards,
8theme team
