This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



Pollux allows you to easily add custom Post Types, Taxonomies, Meta Boxes, Global Settings, Archive Page meta, and more…all within mere minutes.

Instead of drag-and-drop, all configuration is added using simple YAML markup on the Pollux settings page.

Pollux uses the Meta Box plugin to add custom meta-boxes. If the Meta Box plugin is not installed, Pollux will prompt you to do so on the Pollux settings page.

Please see the plugin wiki for complete examples on how to use YAML markup in the plugin. Once you’ve used it, you’ll wonder how you ever managed without it!

Pollux was made to complement themes built on the Castor framework (i.e. Castor), but it can be used with any theme.
