Hi. Something is really bugging my clients. When browsing pages, form time to time the 404 error shows up on existing pages. After a 404 shows up, a press of the refresh button loads the page just fine. It's just annoying as when someone is browsing, the 404 just pops up, and some might think that the server is down when it's not. Anyone else experiencing the same issue? We're running the latest version of litespeed, using cloudlinux for our OS. Please advice.
