Whenever a question is posted, answered, file changes, votes, etc. it appears to intermittently show the new content, but refreshing can then show the old. It's not a cache issue on my end, in fact I have tried with things like Incognito mode and cleared all caches.
I find that if I issue the command: sudo /opt/bitnami/ctlscript.sh restart
That the issue goes away and it's consistent again.
