How to show the subscribe button

The WP Subscribe to Author automatically detects where to add the subscribe information card, but you can also check in the plugin settings and set up custom selectors for that.

If you are looking to add the subscribe button to a certain location, you could use the [subscribe-author-button] shortcode which will actually show it wherever you place it. We recommend to use it on author pages just to make sure the plugin can determine who the user is subscribing to.
