Outputs data stored in HeadSpace2 post meta without requiring HeadSpace2. This allows one to remove the now-unmaintained HeadSpace2 plugin without losing the data associated with legacy content.
The HeadSpace2 plugin is no longer maintained and generates many warnings when used with PHP 7. With this in mind, and without judging the original plugin, I created this option to preserve the plugin’s output for SEO purposes. The plugin does not allow HeadSpace2 data to be edited; it only allows search engines to continue accessing it.
Note that many current SEO plugins also handle migration from HeadSpace2, but since I don’t use any such plugins on my network, I created this alternative.
For a full list of the HeadSpace2 data that’s supported, see the FAQ.
