Homepage still shows “hello world” page after all edits and removings

Your pages are cached server-side using LiteSpeed Cache
You have to install helper plugin and flush cache whenever you do updates, otherwise you can disable cache for site under development in your hosting settings, for more info contact your web host support.

But why are the other pages updating normally and only homepage is being “bugged”. I tried flushing cache, deleting and it still doesn’t work . Do you have any other suggestions?

And one more thing to add is that when I try to open the website thru incognito tab it works normally + for me site is always normal, and for others isn’t. please help
