One of the sites I look after has a peculiar issue with YARPP which I can't quite pinpoint. No related posts are showing the majority of the time, although changing any YARPP options will briefly make them appear again.
My suspicions are on W3TC, which is also installed on the site. Perhaps there is a conflict with YARPP's cache and W3TC? Regardless, any insight into the cause of the problem and a fix would be greatly appreciated.
It's running YARPP 3.5.5, and if it helps the caches enabled in W3TC are the page cache and object cache.
