Just as in the other ticket, I'm not able to see the number of items per page issue, as a logged-in user or as a guest.
Your website seems to be using the LiteSpeed Cache plugin for cache management. Cache plugins usually show cached content for longer durations to guest users, but logged-in admin users are shown updated content.
If you experience unexpected behavior, as a guest user, you can clear all the involved caches and then check the page again.
Thanks for your explanation. Can I make the cached content with shorter durations to guest users? Is it controlled by LiteSpeed Cache, WordPress or Toolset can force the cache to be expired early?
