You might have made some major changes to your website on your administrator dashboard, but on viewing your site in the browser, you find out that nothing changed. You may also have made and saved changes to scripts on your web server, like modifying fields on your contact form. If you are wondering what happened to the changes you made and why they aren’t seen when you preview the site, you should ask yourself if you need to clear or purge WordPress cache.

Your WordPress website may be caching pages with the help of WordPress plugins, and so is your browser. Your updates are likely not showing because your cache plugin has not updated its content to your latest additions, or you have not cleared your browser cache.

A cache plugin is very necessary for the optimum performance of your WordPress website. It enhances website speed by caching pages and loading them to the browser on user requests.

What is caching, and how do cache plugins work?

Caching helps to reduce the time and resources needed to load your site pages. In WordPress, the caching plugin creates and stores a static version of your website’s most requested files.

With the cached content available, WordPress does not repeatedly need to go through the process of loading numerous PHP scripts, pulling database results from the DB, loading JavaScript, CSS and HTML files to the browser on every request.

To make things faster, WordPress fetches the cached version of your web content from the caching plugin and loads them to the browser. This greatly reduces the load time of the website, and the number of server resources it could have used.

Why do you need to clear your WordPress cache?

Since WordPress would rather load content to the browser from caching plugins, there are chances that changes you made directly to your scripts or via the admin dashboard may not reflect immediately when you load the site.

So you have to manually get rid of the static, cached version of your web pages, media, compressed scripts, and stylesheets. You must do that by purging your cache plugin to make room for updates from the server.

It is very important to clear the browser cache frequently. This is necessary for all updates to load on the browser. Most popular browsers always save cached data and the saved data can prevent updates from loading properly.  So it is up to you to manually clear out the browser cache by yourself as it is the only way your updated content can load.
