WordPress is not updating the changes you have made recently? You have changed the theme but WordPress is still showing old theme? Chances are you need to clear caches in order to see the updated results.

Internet caches are used to improve browsing experience by loading static pages or pages from history.

From a blogger’s perspective it could create problems if you update something on your WordPress site, it will show you the cached content instead of showing what you have recently changed. It could be quite annoying.

The solution is to clear all types of caches to get an accurate updated view of your website.

What is WordPress Cache?

WordPress is a database-driven software. What it means every time a URL is requested by a visitor, it needs to connect to database to fetch the page on-the-fly. This could increase website loading time.

To bypass database calls every time, WordPress makes use of caching plugins to save static version of the pages in cache to display when requested. It improves website performance and reduce server load times.
