You’ve probably heard of a browser’s cache before but might not know exactly what it is or why it would be useful. A web browser’s cache is essentially a folder where your browser stores all of the images, videos, and files that it retrieves from websites when you visit them.
This can be very helpful if you have a website with lots of media files like pictures or videos because your browser will be able to load them much faster the next time you visit that site.
The drawback to this, however, is that sometimes your browser will save an old version of an image instead of the most recent one, which can lead to some weird visual glitches from time to time.
It’s not uncommon for WordPress users to run into issues with their site’s performance and its caching system from time to time. In this blog post, we’ll go over how you can clear your WordPress site’s cache and get it running more smoothly for future visitors.
The problem with caching
Your browser typically saves data when you visit a new website, allowing its pages to load more rapidly the next time. But too much of this “cached” data can sluggish your browser.
Additionally, it can keep you from seeing any recent site updates.
You’ll frequently hear that the first step in troubleshooting is to clear your WordPress cache. It’s easy to remove outdated cached info. Regularly carrying out this task will speed up your browsing and enable you to view more recent website versions.
What does “clearing cache” mean?
Data caching typically happens when you visit a website, whether from a desktop, tablet, or phone. To simplify your next visit, your browser will save a few webpage files to your computer. The website will load faster with this cache in place.
Although it is a handy function, it does take up some room. Clearing your cache entails removing any saved information to make room on your server, browser, or device.
WordPress caching is used and implemented in two forms:
1. Client-side caching:
Client-side caching is another term for browser caching. This cache stores static HTML pages locally on the user’s machine. Each time a user accesses the website, a copy is loaded from the user’s computer. Consequently, this approach is substantially faster.
2. Server-side caching:
When you have a large website with numerous databases, server-side caching is utilized. To maximize efficiency, static pages are kept on the hard drive or in the RAM of the website server. This is still quicker than without caching, even though it takes longer than browser caching.
Why do you need to clear the WordPress cache?
The caching system erases obsolete WordPress cache when you make a new post or modify your content.
However, occasionally your caching system could fail to recognize updates and continue to display the outdated, static, cached version. Your site could go down due to a disagreement between the cached version and the upgrades. Here are a few such scenarios when this might occur.
