The easiest way to clear the WordPress cache without using a plugin is to manually delete the cache files from your WordPress installation’s wp-content/cache folder.
Here are the steps:
- Access your WordPress site’s files using FTP or your hosting provider’s file manager.
- Navigate to the wp-content folder and open the cache folder.
- Delete all the files and folders inside the cache folder. Do not delete the cache folder itself.
This will clear the WordPress cache without the need for a plugin.
The cache will automatically rebuild the next time a page is loaded.
Some other options to clear the WordPress cache without a plugin include:
- Disabling caching entirely by adding
define('ENABLE_CACHE', false);
to your wp-config.php file. - Clearing the cache through your web host’s control panel, if they provide that functionality.
- Using the WordPress command line interface (WP-CLI) and running the
wp cache flush
command.
Clearing the WordPress cache regularly can help improve site speed and ensure visitors see the latest updates to your content.
It’s a good practice to clear the cache after making significant changes to your site.

What are the potential drawbacks of clearing WordPress cache manually?
Here is a concise and accurate response to the question, based on the search results:
The potential drawbacks of clearing WordPress cache manually include:
Temporary Performance Drops: When the cache is cleared, the server must rebuild the cached content from scratch, which can temporarily increase load times and server load until the cache is fully regenerated.
Increased Server Load: Frequent manual cache clearing forces the server to repeatedly process and store data, increasing the workload and potentially affecting the site’s overall performance, especially on shared hosting environments.
Content Delivery Interruptions: For sites using Content Delivery Networks (CDNs), clearing cache can lead to temporary inconsistencies in content delivery, as different CDN nodes might serve different versions of the content until the cache is fully propagated.
Loss of Saved User Sessions: Clearing the cache may delete saved usernames and passwords, requiring users to re-enter their login credentials.
Potential Security Threats: Hackers can take advantage of hidden data in the cache to embed viruses, so frequent manual clearing is important for security.
To mitigate these drawbacks, it’s recommended to only clear the WordPress cache when necessary, such as after major site updates, and to configure automatic cache expiration and regeneration settings.
How can you automate the process of clearing WordPress cache without a plugin?
To automate the process of clearing the WordPress cache without using a plugin, you can follow these steps:
- Access your WordPress website’s root directory via FTP or SSH.
- Locate the .htaccess file in the root directory and open it for editing.
- Add the following code to the .htaccess file:
“`
Clear WordPress Cache
ExpiresActive On ExpiresByType image/jpg “access plus 1 month” ExpiresByType image/jpeg “access plus 1 month” ExpiresByType image/gif “access plus 1 month” ExpiresByType image/png “access plus 1 month” ExpiresByType text/css “access plus 1 month” ExpiresByType application/pdf “access plus 1 month” ExpiresByType text/javascript “access plus 1 month” ExpiresByType application/x-javascript “access plus 1 month” ExpiresByType application/javascript “access plus 1 month” ExpiresByType image/x-icon “access plus 1 year” ExpiresDefault “access plus 2 days”
Clear WordPress Cache on Post/Page Update
RewriteEngine On RewriteRule ^(.*)$ $1?v=$1 [L]“`
This code sets the cache expiration time for various file types and also adds a query string parameter to the URL whenever a post or page is updated, forcing the browser to fetch the latest version of the content.
- Save the .htaccess file and upload it back to your WordPress website’s root directory.
With this setup, the WordPress cache will be automatically cleared whenever a post or page is updated, without the need for a plugin.
The cache will also be cleared for specific file types based on the expiration times set in the .htaccess file.
When is it recommended to clear WordPress cache manually instead of using a plugin?
The recommended times to clear the WordPress cache manually instead of using a plugin are:
-
After making significant changes to your website’s design or content. Clearing the cache ensures visitors see the most up-to-date version of your site, rather than a cached version.
-
After updating your WordPress theme or plugins. Plugin and theme updates can sometimes require clearing the cache to ensure the changes take effect properly.
-
When troubleshooting issues on your site. Clearing the cache can help resolve problems caused by outdated or corrupted cache files.
-
When migrating your website to a new domain or hosting provider. Changes to your server and database may require clearing the cache to avoid issues.
-
If you notice your website is not displaying the latest changes, even after clearing your browser cache. This could indicate an issue with the WordPress cache that requires a manual clear.
In general, it’s recommended to clear the WordPress cache manually when you need to ensure visitors see the most recent version of your site, or when troubleshooting performance or display issues.
Using a caching plugin can make the process more convenient, but manually clearing the cache may be necessary in certain situations.
