Why is my WordPress site cached?

Question

caching

There is a site on wordpress, for which caching is harmful, but it is there. Without knowing the source of the caching, I can't reset it to be detected by disabling plugins. There are no caching plugins. Full list of plugins:

.html on PAGES | Version 1.1 | by IntroSites
Advanced Custom Fields | Version 5.8.1 | by Elliot Condon
Akeeba Backup for WordPress | Version 3.4.2.2 | by Akeeba Ltd
Post SMTP | Version 2.0.4 | by Yehuda Hassine
Smart Slider 3 Pro | Version 3.3.21 | by Nextend
Sorting categories and taxonomy (hierarchy) of elements | Version 1.5.5 | by Nsp-Code
Cookie Notice | Version 1.2.46 | by dFactory

Server tech support says there is no caching on their end. So where did it come from, and how can we find out?

Hello!
In general, the cache can be in different places.
1) on the server side - pull the hoster here.
2) browser cache (I'm sure you excluded this option)
3) site cache (plugins Autoptimize, WP SuperCache, Wp Rocket, Wp Fastest Cache, Ninja, Pagespeed, etc.)
4) CDN cache (see if you have a CDN connected maxcdn or cloudflare service). There is also a cache
