Lite Speed Cache Problem

You have an additional CDN cache in use. Disable it and your issue goes away.

I am using Cloudflare but after On the Development Mode Of Cloudfare I am still facing this issue. the issue is only arrises from different non-logged in browsers. From my Pc I am not facing the issue.

That doesn’t matter. There are 2 cache layer in use, but more than 1 cache layer causes conflicts and users always see stale content.

now what’s do next I disbale Cloudflare catching but still facing the problem

Purge cache of cache plugin and check it again. The Litespeed cache plugin purges the cache automatically if there are any changes at a post. If the problem persists, there must be other reasons for this, but first disable this other cache, then we’ll see.

I did it but still facing the issue

Another function is active on your server, which on the one hand blocks/prevents caching and therefore the Guestmode does not work either. What ultimately caused the problem cannot be specified from the outside, but if you look at your response headers, there is an indication that your WordPress installation has been significantly modified. The problem cannot be solved by the plugin support. You have to find out for yourself what could be the cause. However, the problem described is not a problem of the cache plugin, because the problem is caused by your modifications.
