I bought the theme “Blackair - One Page WordPress Theme for Hair & Beauty Salon” and installed it on Wordpress. Now I wanted to install the demo data. Unfortunately, I do not know what data to load now.
Please check the theme documentation hopefully you will get necessary support there. If you have still problem with the theme demo import then The best way to get the support is Contact your purchased Theme Author. Contact Author and let them know because Item Author are best expert about their Item functionality.
Also you can check your theme Option if you find anything related to the demo import.
