We all know that WordPress cache stores temporary website data to improve loading times and enhance website speed. However, outdated or corrupted cache files can cause issues like incorrect formatting, broken layouts, or errors when updating themes and plugins. Clearing WordPress cache is straightforward and doesn’t require technical expertise.
Whether you use plugins or manual methods, the process is simple. For example, e-commerce sites with faster load times often see higher conversions, while slow-loading pages can increase bounce rates. Regularly learning how to clear WordPress cache can significantly improve website performance and user experience.
In this post, you will learn how to clear WordPress cache, ensure your visitors see the latest version of your site and help resolve common problems like troubleshooting errors or display glitches.
What You Need to Clear Cache in WordPress
Clearing the WordPress cache doesn’t require advanced technical skills, but having the right tools and understanding the process can make it much more manageable. Let’s break down the essentials and optional tools that can enhance your experience.
Basic Requirements
You’ll need a few basic resources to clear your WordPress cache effectively. These ensure you can access and manage your website’s cache without complications:
-
Access to Your WordPress Dashboard: Most caching plugins and settings are accessible directly from the WordPress admin panel. This is your starting point for clearing cache using plugins.
-
Hosting Control Panel Access: Many hosting providers, like WP Engine or BlueHost, offer built-in caching tools. For example, WP Engine allows you to purge all caches via the admin bar, while BlueHost provides a similar option under the “Caching” menu.
-
FTP Client or File Manager: If you prefer manual methods, you’ll need access to your website’s files. Use an FTP client like FileZilla or your hosting provider’s file manager to locate and delete cached files.
-
Database Management Tool: Tools like phpMyAdmin let you clear cache values stored in the WordPress database. Always back up your database before making changes to avoid data loss.
Many caching plugins also allow you to manage different types of caching, such as page cache or object cache. Adjust these settings as needed and click “Save Settings and Purge Cache” to apply changes.
Optional Tools
While the basic requirements cover most scenarios, optional tools can optimize the process and improve your website’s performance. These tools are particularly useful for advanced caching needs:
-
Varnish Caching: Speeds up website load times by caching HTTP requests and responses.

This plugin is particularly effective for improving website performance through advanced caching techniques and optimization tools.
Here’s how you can clear your WordPress cache using LiteSpeed Cache.

Log in to your WordPress dashboard. From the admin menu, locate and click on LiteSpeed Cache. This will open the plugin’s settings page, where you can manage various caching options. -

How to Clear the WordPress Cache Without Plugins
Clearing the WordPress cache without plugins is a practical approach, especially if you prefer not to rely on additional tools. Let me guide you through two effective methods: using your hosting control panel and accessing your website files via a file manager or FTP.
Using Hosting Control Panel
Most hosting providers include built-in caching tools that simplify the process of clearing server cache. Here’s how to clear the WordPress cache using your hosting control panel:
-
Log in to your hosting account and access the control panel (commonly cPanel or a custom dashboard).
-
Locate the caching section. Depending on your host, this may be labeled as “Cache Manager,” “Caching,” or something similar.
-
Select the option to purge or clear the cache. Some hosts allow you to clear specific cache types, such as object cache or page cache.
-
Refresh your website to ensure the changes take effect.
While this method is straightforward, it’s important to note potential risks. Clearing server cache can temporarily increase server load as fresh cache files regenerate. This might cause slower load times for visitors during the process.
However, the benefits of displaying updated content and resolving display issues outweigh these temporary drawbacks.
Using File Manager or FTP
If you prefer a hands-on approach, clearing the WordPress cache through a file manager or FTP is another reliable method. Follow these steps to clear the wp cache manually:
-
Access your hosting control panel and open the file manager, or connect to your website using an FTP client like FileZilla.
-
Navigate to the WordPress root directory, typically named
public_html
orwww
. -
Open the
wp-content
folder and locate thecache
directory. -
Delete all files inside the
cache
folder. Be cautious not to delete the folder itself to avoid errors. -
Clear your browser cache and refresh your website to verify the changes.
When using FTP, always proceed carefully. Deleting the wrong files can disrupt your website. I recommend creating a backup before making any changes to ensure you can restore your site if needed.
Both methods provide effective ways to clear cache in WordPress without relying on plugins. Whether you use a hosting control panel or FTP, these techniques ensure your website remains updated and performs optimally.
How to Clear Browser Cache (If Necessary)
Why Clearing Browser Cache May Be Needed
Clearing browser cache becomes essential in several scenarios. I’ve noticed that cached data often causes website errors or prevents recent updates from displaying correctly. For example, after making CSS or JavaScript changes, the browser might still load outdated files, leading to formatting issues.
Similarly, updating themes and plugins or migrating to a new host can result in inconsistencies if the cache isn’t cleared.
Website redesigns or new plugin installations also benefit from clearing the cache. This ensures visitors see your site’s latest version without interfering with outdated elements. This is particularly important when compressing images or publishing new posts and pages.
Cached data can prevent these updates from appearing as intended. Regularly clearing browser cache ensures the most recent version of your website is live, eliminating display inconsistencies and outdated content.
Steps to Clear Browser Cache
Clearing the browser cache is straightforward and varies slightly depending on the browser. Here’s how you can do it for the most popular options:
-
Google Chrome
Open Chrome and navigate to Settings > Privacy and Security > Clear Browsing Data. Select the Advanced tab to view additional options. Check the boxes for cached images and files, then click Clear Data. This ensures the browser fetches updated website elements. -
Mozilla Firefox
Click the menu icon and go to History > Clear Recent History. Use the dropdown to select the time range and check the Cache option. Click OK to clear the cache. This resolves display issues caused by outdated data. -
Android Devices
Open your browser and access the settings menu. For Chrome, go to Privacy and tap Clear Browsing Data. Ensure the cache option is selected before confirming. This process refreshes website elements on mobile devices. -
iOS Devices
From the home screen, go to Settings > Safari. Scroll down and tap Clear History and Website Data. Confirm the action to clear cached files. This step is crucial for resolving display issues on iPhones and iPads.
Clearing browser cache improves loading times and prevents formatting problems. It provides a clean slate for the browser, ensuring it retrieves the latest website data. I recommend performing this task regularly to maintain optimal website performance.
Potential Challenges and Common Mistakes When Clearing WordPress Cache
Challenges You Might Face
Clearing the WordPress cache can sometimes present unexpected challenges. I’ve encountered several common issues that users face during this process:
-
Recent changes to posts or pages may not appear immediately. This often happens when one or more types of cache fail to recognize updates.
-
Updates made through the WordPress customizer might not display correctly. Cached files can interfere with the visibility of these changes.
-
New images, pages, or posts may not load as expected due to caching software retaining outdated versions of your site.
An outdated cache can also lead to performance issues or errors on your website. For example, the cache may still serve older versions after updating themes, plugins, or CSS/JavaScript files. This can confuse visitors and harm your site’s credibility.
I recommend clearing the cache directly through your caching plugin’s options page to address these challenges. This ensures all cached data is refreshed and your site displays the latest updates.
Common Mistakes to Avoid
When clearing the WordPress cache, users often make mistakes that can prolong issues or create new ones. Here are some frequent errors I’ve noticed and how to avoid them:
-
Forgetting to clear the browser cache. This can prevent you from seeing updates on your site, even after clearing the WordPress cache.
-
We need to consider the need to clear different types of cache, such as object cache or CDN cache. Each type affects your site’s load, so neglecting one can cause persistent problems.
-
Failing to clear cache from WordPress caching plugins. This mistake often results in outdated content being displayed to visitors.
A stale cache can damage user experience and reduce your site’s performance. Regularly clearing all relevant caches ensures your website remains fast and up-to-date. To avoid these mistakes, I recommend creating a checklist for clearing cache across all tools, including plugins, hosting control panels, and browsers. You can maintain a smooth and efficient caching process for your WordPress site by addressing these challenges and avoiding common mistakes.
Clearing the WordPress cache is essential for maintaining a fast, responsive website with the best user experience. Regularly clearing your cache reduces load times, which improves SEO rankings and attracts more visitors. It also ensures your site operates smoothly, displaying the latest updates without errors.
You can clear the wp cache using plugins like WP Super Cache or W3 Total Cache, which simplify the process with user-friendly interfaces. Alternatively, non-plugin methods, such as using your hosting control panel or FTP, provide a more tailored approach.
Don’t forget to clear your browser cache when necessary to resolve display issues.
I recommend clearing the wp cache after updating themes, plugins, or CSS files. This habit ensures your site remains optimized and error-free. The process is straightforward and manageable, even for beginners. With these methods, you can confidently clear cache in WordPress and keep your site running at its best.
FAQ
What happens if I don’t clear my WordPress cache regularly?
Outdated cache files can cause display errors, slow loading times, and prevent updates from appearing. Regularly clearing your cache ensures visitors see the latest version of your site and improves overall performance. Neglecting this step may harm user experience and SEO rankings.
Can clearing the cache break my website?
No, clearing the cache won’t break your website. It only removes temporary files stored for faster loading. If issues arise, they’re usually due to unrelated factors like plugin conflicts or server errors. Always back up your site before making significant changes for added security.
How often should I clear my WordPress cache?
The frequency depends on your site’s activity. For high-traffic or frequently updated sites, clear the cache weekly or after major updates. For smaller sites, monthly clearing works well. Regular maintenance ensures your site remains fast and displays the latest content.
Do I need to clear my CDN cache too?
Yes, if you use a Content Delivery Network (CDN), clear its cache after updating your site. CDNs store cached copies of your site on multiple servers. Clearing this cache ensures visitors receive the most recent version of your content, regardless of their location.
Is clearing the browser cache necessary after clearing WordPress cache?
Yes, clearing the browser cache is often necessary. Browsers store cached files locally, preventing you from seeing updates even after clearing WordPress cache. Refresh your browser or use incognito mode to verify changes if clearing the cache doesn’t resolve display issues.
