Page Caching Problem after Upgrading
I recently upgraded my wordpress instance from 3.5.1 to 3.8, and upgraded W3TC to 0.9.3. Since then, I've noticed updating WP Pages doesn't flush the Page Cache. I'm using Memcache as the backend, but I've also tested with APC and File. All show the same problem.
How I test:
- Update the content of a page via Wordpress
- Access page URL through "Wordpress Address": the updated content is visible
- Access page URL through "Site Address": the update is not reflected
- Empty Page Cache
- Access page URL through "Site Address": the updated content is now visible
If this is not a known issue, can someone direct me to debugging tools? I'm curious to know if the relevant W3TC functions are being called on WP's "save_page" action.
