Thank you, but now I am confused ??

I did read on the Guest mode and there is a question that remains:

Documentation says that cached version is loaded, then Ajax call is made and “real” page loads, so “broken” page should only be visible for the short time, right?

I quote: “Once the HTML of the page is loaded, then an Ajax call is used to load the “correct” version of the page for that visitor (i.e., the one where ESI and cache varies are considered, and whatever optimizations you normally run on your site are used).”

In my case “broken” layout remains and is never refreshed

I foolishly cleared cache on the couple of items affected. Will wait a day or two . hopefully more USA customers will visit and I will check out styles they buy.

Keep in mind, it takes time for Litespeed cache to actually kick in. It is not instant. May take a day or so before it is fully processed the page

No

Cache Mobile is off. Never tried to enable it. I am turning options on one at a time, let cache generate, make sure it is good, then try next option.

An update — User Agent seem to be set up correctly by Chrome on my Linux PC, but not set up correctly by Chrome on my Mac, this is how I noticed it.

In any case, it appears that changing user agent, behavior changes. At the moment, I was able to reproduce issue on desktop, found missing CSS class, updated UCSS white list and cleared all caches. Fingers crossed, problem is gone now

Thank you, all fixed.

Changing the option mentioned fixed memory problem.

As for the feed, problem was actually on my side. Some time ago, my site used different directory structure (“content” instead of “wp-content”). I fixed this over a year ago and set re-direct from old URL structure to a new one, so everything was working. Something happened to re-direct about a week ago and this broke feed. Not sure why Google just would not tell me it is unable to load the feed and would complain about feed structure instead.

Yes, correct. Problem is reproducible.

I will raise a ticket

None I am aware of.

By the way, this happens very rarely. If this would be a result of a protection or like, I would expect it to be seen much more regularly

If I follow link, it loads just image as expected.

Yes, was always off. i am using Optimole plugin that converts images to WebP and serves them from CDN, so I did turn off all image optimisation options in LiteSpeed right away.

I still see same. This is today screenshot

Still fighting problems, but getting there.

original issue was caused by DNS failure somewhere and one of the third-party resource was not found. This process was taking a long time

What theme?

I was just fighting similar on Avada theme.

Problem is caused by UCSS or, rather, incompatibility of the theme with Litespeed UCSS generation.

On the very top in Litespeed Cache Dashboard you will see:

QUIC.cloud Service Usage Statistics and “Sync” next to it. Just click on Sync

I fixed it for most parts now. Had to do a small mod in the theme as well as adding CSS classes in UCSS tuning.

Newly generated page — still broken,

Here is a link to one of the pages just updated (problem is in the same place as on main page):

Thank you,

I think I found it — third-party JS script is not loading, causing long timeout
