Occasionally, once a week or so, w3tc stops updating the cache. It shows data a day or two old on my home page, rather than picking up the more recent posts.
When this happens, I tell it to empty the caches, but it usually churns and churns, never finishing the emptying process (I have waited 30-45 minutes). At that point, I deactivate it and reactivate it. This seems to resolve the problem, and for several days all is well. But then it happens again.
It has happened for me for 6-8 months, so it occurred both before and after the most recent update.
Anyone else had this problem? Have you found any permanent cure? Or a less time-intensive way to clear the cache? For example, does deleting a particular file (wherever the cache is held) effectively clear the cache and force w3tc to recreate the file to start caching again?
