Hi isacuhaci,
It is recommended to run import on a fresh WordPress installation. For this you can use 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.
Then, I kindly request you to read and adhere to the steps outlined in our theme documentation, which can be found at the following link: https://xtemos.com/docs-topic/installation-process/
If you have any further questions, please don’t hesitate to reach out.
Regards,
