What Is an Ocean Demo?
Ocean Demos are pre-built OceanWP theme layouts that serve to speed up the website building process.
Ocean Demos are not individual or separate themes, therefore you will not find them within the Themes section (Appearance > Themes).
In order to import an Ocean Demo, you need to have the OceanWP theme and Ocean Extra plugins installed and active on your website.
If you want to import an Ocean Pro Demo, you need to have the Ocean Pro Demos extensions installed on your website and activated using your license key.
