How to clear the WordPress cache without using a plugin?

What is Caching?

Caching is a process of storing copies of the website file in a cache or temporary location so they can be accessed more quickly. The caching process helps improve the speed and performance of WordPress and the overall user experience.

WordPress has different types of caching solutions. The most common way is to use a WordPress caching plugin such as WP Rocket or WP Super Cache. These plugins allow you to control which files and media are cached when the cache expires, when the cache is cleared, and more.

Why do we need to clear the cache of the WordPress site?

Sometimes the cache doesn't show the changes you made on your WordPress site. Instead of loading the new version of the website, only the old version is displayed. This prevents both you and your visitors from seeing any updates you make. Clearing your WordPress cache will always enable the latest version of your site.
