Hello, JS7319,
Thank you for reaching out and providing detailed information about the issues you’re encountering with the installation of the 3 furniture demo on your website.
Upon reviewing the details you provided, we discovered that the problem was due to an incorrectly specified template in the file
/wp-content/themes/child-theme-xstore/style.css
The template was incorrectly listed as Template: Parent Theme XSTORE, whereas it should have been Template: xstore.
We have corrected this issue, and you should now be able to proceed with the installation of the demo data without further problems. Please try reinstalling the demo and let us know if you encounter any more issues.
Thank you for your patience and cooperation. We are here to assist you every step of the way.
Best Regards,
The 8Theme Team
