Reply To: AJAX import error. Try to disable all external plugins and run the import again.

This problem is not caused by our theme. You will not be able to use your website while you have a problem with URL configuration.
If you can’t change this, you can request a refund here https://themeforest.net/refund_requests/new
But take into account that other themes will not work correctly as well because of this.

Kind Regards
