Re: Hummingbird – My cache keeps emptying out and starts over every couple of days. I do not believe that should happen. I had a couple hundred pages cached as of yesterday and they are gone today and starting over. Third time this has happened. Also, my website's performance test is at 77. Even with more pages cached I still tested at 77. This is about where I was before I installed Hummingbird & Smush Pro. Thanks!
