In addition to all the settings under the “Customize” link, the PublishPress Theme has some additional settings.
To find these setting, go to Appearance > PublishPress Theme in your WordPress admin menu.
Here you have a few settings for WordPress posts, breadcrumbs and WooCommerce display.
Be careful with this setting. The reset button is very useful only if you want to reset the theme to its defaults. We are talking about the design aspects: layout, colors, fonts, backgrounds, etc. It doesn't affect the content.
