Cache is useful to speed up website. But cache becomes a problem when we update plugins or upgrade WordPress themes. WordPress is fairly database intensive so it’s highly recommended to host your WordPress site with a webhost that provides built-in caching tools or to use a 3rd party Caching plugin. Any website will only have one of the caching methods described below.
Hosting Cache
Most webhosts have builtin cache functions that can be easily flushed / cleared. Below is explained methods to clear cache in some of the popular web hosts.
