What to see at log file, in order to check if something used the “purge all” function?
I monitor the crawlers that running all day, and all the time i get cached pages, except when new order created (even when a user checkouts, even if an third party plugin creates the order).
After any new order i get “cached missing” pages.
It look like that after that action (it’sa plugin that creates new orders from marketplace to woocommerce, the same behavior I have when i place an order as guest), all product pages are served uncached!
