I’ve noticed throughout the week, some of my sites on different servers (AWS, Linode, Vultr) sometimes show up as a blank white page (empty) and refreshing does not fix it. I can still login and go to dashboard. The blank site is fixed only after I purge Varnish cache. I have the Breeze plugin set to purge every 20 hours as well.
I was wondering if anyone has had this problem and what you did you mitigate this? I am also wondering if increasing the WP memory limit may help remedy this or if this is a varnish configuration problem.
