Flushing cache works. But everytime I click on "Build cache now", YARPP Experiments will start working and then aborting around 75 percent or so, saying: "Cache computation ended prematurely. Try reloading the page and continuing."
This occurs everytime - I never got it to build the cache to the full. I had a look at other plugins that might interfere with YARPP (e.g. Cachify) and turned them off - nothing changed. I'm at a loss here. Ideas?
