Organica theme "Import data demo with One Click" showing error

I have purchase organica theme from envanto. I have installed the theme but it’s looking so ugly and not appear as i have seen in the demo before making a purchase.

I have also installed the recommended plugins.

But when we do “Import Data Demo with 1 click” showing an error.

error message “This does not appear WXR file, missed/invalid WXR version number”

Please get in touch with the author of the theme to get support:
