Your web browser, caching plugin, CDN as well as hosting, can serve cached content which can make it difficult for you and your site visor to see the changes you made to your site right away.
Clearing your WordPress cache is the first troubleshooting advice any WordPress expert will give you in this situation.
In this post, I’ll show you how to quickly clear the cache for all the major browser, CDN, and all the major caching plugin, including WP Rocket, W3 Total Cache and WP Super Cache.
Regardless of whether the issue is browser-based or server-based, by the end of this post, you’ll be seeing the most up-to-date version of your WordPress site.
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:
A 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However, sometimes outdated cache can stop you from seeing the changes you made on your site.
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.
01. Clear Your Browser Cache
Modern days browser like Google Chrome and Firefox comes with an integral caching system that stores static content of a website to make it load faster in the next visit.
However, sometime your browser may fail to realize that the web page has been updated with new content. That’s why instead of fetching a new fresh copy they may show you the previous copy of the web page stored on browser data storage.
In this situation, you have to manually clear your browser cache to see the updated copy of your web pages.
