In this article, we will show you how to fix Word Press website not updating right away.
The most common symptom of this problem is new posts not appearing on the homepage of your Word Press site.
I noticed recently that the full page cache for category pages isn't getting updated. There are two 'expires' setting you can configure in W3 Total Cache, one is the static page cache on your server, the other is the browser cache settings that the browser will use to decide whether to use a local cache for a page, or to re-request that page from the server. Depending on the browser involved, it would require manually clearing the cache to get the browser to fetch the page from the server, rather than pulling it from the local cache on disk.
Other pages seem to work fine (home, posts, etc) but categories cache files stay untouched for days until I manually rm -rf them. There's also potentially caching proxy servers that might exist between you and the server - that could also come into play - which could be the case in a corporate setting.
When a new version of Word Press is available you will receive an update message in your Word Press Admin Screens.
