The WordPress Pantheon Advanced Page Cache version 2.1.1 update is now available. This latest update resolves a bug that caused some sites to cache 404 pages, leaving scheduled posts unavailable after publishing.

What's new?

  • A post's path is explicitly purged when it is published for the first time, in addition to related surrogate keys.
  • Purged paths can be further customized with the pantheon_clear_post_path filter.

Upgrade the plugin now in your WordPress admin to take advantage of these improvements and make the most of Pantheon's edge caching layer or learn more about Pantheon Page Cache in our documentation.
