Not working in WP 6.4.2

Installed the plugin, I can see the settings page, but the Series meta box on the post editing page is not showing. This topic was modified 2 years, 3 months ago by agilistandre.

still great

I’ve been using Series for ages and it still works great. Now I use PHP 7.1 and WordPress 5.4.1. Thanks to Justin Tadlock for this plugin.
