Hi JN,

Indeed all pages are stored in Joomla database.

You have to find table PREFIX_sppagebuilder

for example jos_sppagebuilder

then inside you have all pages with their own unique ID and name.

1. Export table as file and Import inside new database. Use PHPMyAdmin from cPanel.
2. If on that page you used images (files), remember that they have to be transfered by FTP as well.
3. I would recommend to export-import also prefix_spmedia table

If you used inside Page Custom CSS or Addon Custom CSS area - should be inside that page, but I cannot tell you where is exactly - genereted page code can be VERY long & complex but custom CSS is inside it (somewhere). Sorry, it's your task to find it.

But if you used inside Template Options > Custom CSS > it's easier to find. In prefix_template_styles
