It’s not a plugin, James. It’s an option with the theme Techknowledgic is using.
Thanks for catching that!
Techknowledgic, if hitting that Purge SG Cache button made no different, I recommend that you go to the theme’s official support channel. In order to be good stewards of the WordPress community, and encourage innovation and progress, we feel it’s important to direct people to those official locations.

Forum volunteers are also not given access to commercial products, so they would not know why your commercial theme is not working properly. This is one other reason why volunteers forward you to the commercial product’s vendors. The vendors are responsible for supporting their commercial product.
In addition, Techknowledgic was referring to the browser cache, not a plugin cache.
Yes, and he’s using SiteGround, which has its own built-in caching. Note the “Purge SG Cache” button in the admin bar in the same screenshot. That’s why I mentioned plugin or server-level caching in my first reply. It’s a common source of “I don’t see my changes” problems.
It started after the last update, which was full of bugs.
This has absolutely nothing to do with the last update, nor is it “full of bugs.”
It would be great if you didn’t pin up the latest version of WordPress as the source of everyone’s problems. It distracts everyone from finding a solution to whatever their real issue is.
