Sometimes you need to copy the entire site along with the settings and content. The easiest and fastest way to duplicate the website is:
- Copy YOUR_SITE folder (Documents ▸ Publii ▸ sites ▸ YOUR_SITE) and move it to the other localization e.g. desktop
- Change the name of your website (Publii - Site Settings)
- Copy YOUR_SITE folder back again (from the desktop) to the sites folder (Documents ▸ Publii ▸ sites)
- Restart the Publii app.
