If you are a WordPress website user, you might have encountered performance issues and slow loading times many times. One effective way to improve your site’s speed and responsiveness is by implementing caching. However, there are times when you need to clear the WordPress cache to ensure that your website displays the latest content and changes correctly. In this article, we will guide you through five different methods to clear the WordPress cache effectively.
Understanding How to Clear WordPress Cache
What is Cache on the website?
Cache, in the context of a website, refers to storing specific data temporarily to reduce load times and improve overall performance. When a user visits a website, the browser requests various assets like images, scripts, and stylesheets from the server. The server processes these requests and sends back the requested files to the user’s browser, which can sometimes cause delays. Caching helps store static versions of these assets, so subsequent visits to the same website load faster.
Importance of Caching in WordPress Website
WordPress caching is essential because it helps reduce server load and decreases the time it takes for pages to load. This results in a better user experience, increased page views, and improved search engine rankings. Caching plugins store generated HTML files, enabling the website to serve these files directly to users without going through the entire process of generating the page every time someone visits.
Why You Should Clear WordPress Cache?
Clearing the WordPress cache is necessary in specific situations. When you make changes to your website, such as updating content, themes, or plugins, the cached files may not reflect the recent changes immediately. As a result, visitors might still see the older version of your site. To avoid this, you need to clear the cache, ensuring that visitors always see the latest version of your website.
Method 1: Clearing WordPress Cache Using Plugins
Clearing the cache manually can be time-consuming, but luckily, there are many WordPress caching plugins that simplify the process. Follow the below steps to clear the cache using a plugin:
- Login to your WordPress dashboard.
- Navigate to the Plugins section and click on “Add New.”
- Search for a caching plugin that suits your needs (for example – WP Rocket, WP Super Cache).
- Install and activate the chosen plugin.
- Access the plugin’s settings and find the option to clear the cache.
- Click on “Clear Cache” or similar, and the plugin will handle the rest.
Method 2: How to Clear cache from WordPress?
WordPress itself provides a built-in caching mechanism that can be easily cleared via the dashboard. Here’s how you can do it:
- Log on to your WordPress admin panel.
- Click on “Settings” and then select “General.”
- Scroll down until you see the “Clear Cache” or “Purge or Clear Cache” options.
- Click on the button to clear the cache.
Method 3: Clearing Cache via FTP
If you are comfortable with using FTP clients, this method is easy for you. Follow the below steps:
- Connect to your website via FTP using an FTP client (for example – FileZilla, WinSCP, Cyberduck).
- Navigate to the root directory of your WordPress installation.
- Locate the “wp-content” folder and open it.
- Look for a folder named “cache” or “caching” and delete it.
Method 4: Clearing Cache from the Hosting Control Panel
Many website hosting providers offer integrated caching solutions with control panels. Here’s how you can clear the cache from the hosting control panel:
- Log in to your hosting account control panel (for example – cPanel).
- Find the caching options or tools section.
- Look for options related to cache management.
- Click on “Clear Cache” or similar.
Method 5: Clearing Cache via Content Delivery Network (CDN)
If you use a Content Delivery Network to improve your website’s performance, you may need to clear the cache there as well. The steps vary based on your CDN provider, but generally, it’s done through the CDN dashboard. Follow the instructions provided by your CDN service.
Best Practices for Cache Management of WordPress
