I have a website that is already running the generatepress theme. I would like to copy the settings, layout, colors from that site and import to a new website so that I do not have to go through the process again.
Are you referring to the Customizer settings? If so, you can go to Appearance > GeneratePress, and export All customizer settings in the Import / Export section. If you have custom CSS in Additional CSS, you’ll need to manually copy and paste this.
