Hello,
Thank you so much for purchasing our theme and contacting our support center.
It seems that the Elementor plugin was disabled when you imported the dummy content. To resolve this, ensure that the plugin is active. Then, navigate to WoodMart -> Prebuilt websites and click on the button to remove the previously imported data. Once this is done, you should be able to import any website without issues. Please test this solution and let us know how it works for you.
Kind Regards
