If you’re running a large website, with lots of visitors, caching can be an important tool to optimize page load times. Find out why caching is important in this article. When using a WordPress caching plugin, you may find that changes made to your WordPress site from the administration dashboard aren’t immediately shown to users in the front-end of the site. This is because WordPress is still displaying the cached version of your posts and pages. To resolve this issue, you need to “clear” the cache, deleting the stored, static versions of your pages and forcing the WordPress plugin to store refreshed pages that include your updates.
In this guide, we’ll show you how to clear the cache on two popular WordPress plugins, W3 Total Cache and WP Super Cache.
Clean CDN Cache
If you’re using a CDN the process is basically the same with one caveat: it’s better not to purge the entire cache. The process itself will vary depending on your host. One popular CDN is CloudFlare. Some hosts such as SiteGround even give you access to the free version of Cloudflare with your account.
Finally. find your settings tab within your CDN settings, and find the Settings tab. You will then see a Cache Purge option with a Purge button to the right. Simply click it, and all of your site’s cached files will begin to purge and regenerate to clear up any issues that might have arisen.
Clear the Cache in W3 Total Cache
Log in to the WordPress dashboard and, in the left sidebar, navigate to Performance > Dashboard. At the top of the W3 Total Cache dashboard, click Empty all caches.
Clear the Cache in WP Super Cache
Log in to the WordPress dashboard and, in the left sidebar, navigate to Settings > WP Super Cache. In the WP Super Cache settings page, click Delete Cache.
WP Fastest Cache
All you need to do is go into the main WP Fastest Cache item in the dashboard, click on the Delete Cache tab, and you will see two large blue buttons. One will be labeled Delete Cache, which does exactly that. And the second is Delete Cache and Minified CSS/JS.
If you’re truly having issues, getting rid of minified files, too, can help. The plugin regenerates them as it does its thing in the future, the same as the cache itself.
Moreover, if you need timeout rules, you can set them all right here, too. Just press the Add New Rule button, and you can set the length of time that your site will wait before loading the page regardless of other caching settings.
On Your Browser
The clearing of browser cache is only something you can do for your own device. If you suspect the cache issue is occurring on a larger scale, skip down to one of the options below. If not, start here.
This is an example of how to clear cache in Chrome. You can clear cache for your WordPress site from the History or Settings tabs. Once selected, navigate to the “Clear Browsing Data” section. Your browser will display the following pop-up. In this screen, you can clear browsing data for cached images and files. This will delete the cache from all websites in your browsing history.
If you want to clear cache just for your website, return to Settings and go to Content Settings: Next, click on Cookies. Firstly, expand on “See all cookies and site data”. Secondly, do a search for your website. Finally, you can then go through and clear all data.
If you work in another desktop or mobile browser, refer to VisualModo’s quick reference guide on how to clear cache in all major browsers. Or, follow this handy guide put together by Indiana University.
