I spent HOURS trying to figure out what was wrong with our caching. That's when by coincidence, when my server admin sent me a screenshot of his dev tools, I saw "flying proxy CDN". I was like.... You gotta be kidding me! I tried out this service for an hour but then realised I wanted to go back to cloudflare. So I deleted the plugin and changed DNS A records back to original in cloudflare. Apparently, flying proxy was still interfering somehow, because no matter what I tried, cache would not update. We tried everything, deleting browser cache on multiple devices, restarting litespeed server, purging cloudflare 100 times and even stopping all service. Well, it seems that flying proxy was the issue even though I deleted the plugin and changed the DNS records in cloudflare. A database search found an orphaned table with the API key which was on autoload. As soon as I deleted that table and deleted my site on flyingproxy.com, the issue was resolved. So why 5 stars? Because the plugin is brand new (so to be expected with bugs) I appreciate what you do and your Facebook group rocks. But please, do not let anyone experience this again because I wasted an ENTIRE DAY of work to fix this annoying little issue. Granted, i'm not a pro developer at all, but still. It was extremely frustrating to deal with. Not knowing what causes your website not to update when you delete all cache, disabled ALL plugins (yes, I even tried that), etc etc etc. Man. I'm happy my site works again.
