Started out awesome but 2 days in, had to deacticate APO. Firstly, post cache wasnt clearing at all. Had to manually purge. Second, I run an ecommerce website and in those 2 days, customers received 403 Forbidden notices on PayPal and/or Stripe checkout – meaning no sales came through. I assume it has something to do with the caching mechanism. I use wp-rocket which had Cloudflare addon disabled. I’m guessing APO should run without any other caching plugin on site? Mmmh. Otherwise saw a significant change in TTFB.
