I am setting up a few sites and would like them all to look similar. I’ve made a good amount of customizations to one theme and I’d love to export and install them on another site.
Is this at all possible to make essentially a copy of the theme and GP settings, elements and all?
Theme settings can be exported / imported in Appearance > GeneratePress.
Elements are a post type so can be imported and exported using the WP Import / Export tool.
If you want to do all together the best bet is to use a Duplicator or Migration plugin
