I’m also having trouble making edits without the updated version of Humanity theme. I am running the latest version of WP. Is there an easier way to install the latest version of your theme? When I uninstall the old theme and then upload the new one, I loose all the theme settings. And, I made a lot of customization to this theme not just in custom css but in editor > header.php. Would it help if I would have created a Child theme?
