How To Clear WordPress Cache
If you have a WordPress website, there are many things that you could do to improve its performance. One of them is to enable caching. So, what exactly is caching and what does it do? Why should you do it? Before jumping into ways on how to clear WordPress cache, let’s first take a look at why you should clear your cache and how it can help you.
Why Should You Clear Cache on Your WordPress Website
Primarily, we use website caching to offer a better experience to the visitors. Caching saves a static copy of your website, which is easier and faster for it to pull up for every visitor. However, it might somehow backfire as well. Anytime your WordPress website experiences the slightest change, caching might not work as you would expect.
However, you can always clear it manually since not doing so could obstruct new information being accessed by the visitors. Some changes in the website design or the content might not be seen in the front-end. This means that the caching system has not detected it yet. Similarly, most websites post new content related to their industry, such as blogs or shop or product information, and so on. Search engines keep an eye and remember each such occurrence. So, the more the quantity and the better the quality, the higher your website is likely to be ranked. However, if your web server doesn’t display your updates, the search engines would not be able to find it.
Another reason for clearing WordPress cache is regarding its updates. Every time new plugin and themes updates take place, it is advisable to clear the cache to make sure that any and all changes made will reflect on the website. Some web hosts, such as GoDaddy, mention that not clearing the cache could cause issues. Changes to your database might also require you to clear the cache so that the visitors experience the best you have to offer. If you are using a WordPress plugin to optimize or enhance your images, you might sometimes come across a case where your server is still using the older version. To make sure it uses the correct version, it is advised to clear the cache.
How to Clear Cache on WordPress Websites
There are multiple ways you can clear the WordPress cache. If you work on WordPress, there is a high chance that you might have made changes but it didn’t reflect. While most of the times this could be due to not saving or publishing after the changes. But, it could also be due to the website cache. Sometime, you may have to manually clear the cache to see the changes on the front-end. Let’s start!
Clearing cache on your browser
Do note that you can work on browser cache clearing only for your device. Let’s take the example of a Chrome browser.
1. The first step is to head to the Chrome browser settings. You can clear the cache for your WordPress website by visiting the History tab or the Settings tab.
2. Once you select it, go to the “Clear Browsing Data” option. You are likely to receive a pop-up. Here, you will be able to clear browsing data for all cached elements, including files and images. Doing this operation will delete the cache from all the websites in your browsing history list. If you want to do it only for a specific website, go to the main Settings menu and head to the ‘Content Settings’. Click on Cookies and expand the selection by clicking on ’See all cookies and site data’. Search for your website and once you find it, clear its data.
Clearing cache with the WordPress Caching Plugin
You are most likely to already have a caching plugin on your WordPress website. If not, don’t fret. There are plenty of great caching options out there. Do your homework and install a plugin that is perfect for your use. For your reference, some of the best ones are the ones created by Search Engine Watch. This includes popular options like W3 Total Cache, WP Super Cache, and WP Fastest Cache.
If you are using the first option, head to the Performance menu. Click on the settings for the plugin to start with the process. Move down the page and note down the caching settings of each. You will be able to do one of the two – either empty cache or instantly purge all cached content.
If you plan to use WP Super Cache, it is far less complicated than the other options available out there. However, this also means that you will not have a lot of control over the data to be cached. It is a simple enough process. You can do this by one of the three tabs – easy tab, admin toolbar, or the contents tab.
Clearing Cache with Managed WordPress Hosting
Caching on server end can include object caching, MySQL caching, and PHP caching. Since website caching only clears the files and other content, you might still face issues. If that is the case, you need to clear the cache from your server as well. If you are using shared hosting, you might not be able to do this. However, if you are with SiteGround or other web hosts who allow it, you would be able to clear the cache from the control panel.
Caching is an important mechanism that helps run your WordPress website smoothly. Manual cache clearing becomes necessary at times. It is not as difficult to perform as it is made out to be! Follow the process mentioned above and you will be fine.
