[page_hero_gravatar]

Your web browser, caching plugin as well as your hosting can all serve cached content which can make it difficult for you to see the change you made to your WordPress website.

In this post, I will show you how to clear WordPress cache in just few minutes.

What is Cache?

In simple computing term, cache is a location where the web pages data and other elements stored, so they can be retrieved quickly.

According To Wikipedia:

cache is a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere.

There are many different types of caching solutions available:

  • Browser cache – A place on your computer or mobile where the browser stores the information of the website which you visit. Rather than downloading information every time you visit the same website, the browser pulls the information from their store. That’s why the website load faster and less mobile data is used for accessing web pages.
  • Cache Plugin – Cache Plugins like WP Rocket, W3 total cache or WP Super cache offer an easy to use interface for controlling what to cache, when to expire cached content, and cleaning up the cache on demand.
  • Server Cache – This type of cache is created on the cache server by your website hosting.
  • CDN Cache – If you are using a free or premium CDN like Cloudflare, then they would also serve cached copies of your website content.

The main purpose of any type of caching is to speed up a website and improve the overall user experience.

However sometime Caching causes you to not see the changes you make on your website right away.

For example – You changed the color of your website From “Red” to “Blue” but your website is still showing old “Red” color.

So, in this situation, you have to manually clear caches to see the changes you made earlier

  1. This is really a good content to read. Especially never read such a detailed guide on Cache. You have explained every single aspect of the cache. In case of WordPress blog, I have recently bought WP Rocket and looking forward to use it on my website. Let’s see how things change. By the way, W3 Total Cache is doing an awesome job as a free one.
