Hi Ludwig,
Thank you for buying our theme. We hope it will meet all your expectations! 🙂
Could you provide us with screenshots of your website please? Please don’t hesitate to comment or highlight your screenshots to help us better understand your issue.
If you’re convinced that something went wrong during the import, it’s recommended to address the issue right now as it might lead to other problems in the future. In this case, we really suggest you to reset your WordPress database using WP Reset (https://wordpress.org/plugins/wp-reset/) and start fresh with our setup wizard. You can easily install the theme by relaunching the setup wizard, as it will programmatically do every steps for you.
Regards,
