How to Clear Cache In WordPress Without A Plugin?

14 minutes read

To clear the cache in WordPress without using a plugin, you can follow these steps:

  1. Manually Clear Browser Cache: When making changes to your WordPress site, the browser often caches certain elements. To clear the cache related to your site, simply press Ctrl + F5 (or Command + Shift + R for Mac users) on your keyboard. This will force the browser to reload and fetch the latest version of the page.
  2. Clear WordPress Theme Cache: WordPress themes often use caching to optimize site performance. If you're making changes to your theme and need to clear the cache associated with it, you can do so by accessing the theme settings or options panel. Look for a "Clear cache" or similar option provided by your theme developer.
  3. Clear WordPress Object Cache: The WordPress Object Cache stores database queries and other data to optimize performance. To clear this cache manually, you need to connect to your server via FTP or access the File Manager in your hosting control panel. Locate the "wp-content" folder and find a file named "object-cache.php" or similar. Delete this file to clear the object cache.
  4. Clear CDNs and Cache from Hosting Provider: If you're using a content delivery network (CDN) or have caching features offered by your hosting provider, you may need to clear those caches separately. Check your hosting control panel or CDN provider's documentation to find instructions on how to clear their caches.


It's important to note that manually clearing the cache in WordPress may not be as efficient or comprehensive as using a cache plugin specifically designed for this purpose. However, if you prefer not to use plugins or have limited options, following these steps can help you clear the cache and ensure your WordPress site reflects the latest changes.

Can clearing the cache affect the performance of your website?

Yes, clearing the cache can affect the performance of a website. Caches store temporary data to help reduce load times and improve performance by delivering content quickly. When the cache is cleared, the website may need to rebuild the cache, which can cause a temporary decrease in performance until the cache is populated again. Additionally, if there are any issues with cache configuration or caching plugins, clearing the cache could potentially cause performance issues if not configured properly.


What are the common issues that can be resolved by clearing the cache in WordPress?

Clearing the cache in WordPress can help resolve a number of common issues, including:

  1. Page or post not showing recent changes: Sometimes, even after making changes to a page or post, the website may still display the older version. Clearing the cache can ensure that the most recent version of the page is displayed.
  2. Layout or design issues: Cached files can sometimes interfere with the layout or design of a website. Clearing the cache can refresh the cached files and resolve any layout or design issues.
  3. Slow website performance: Caching helps speed up a website by storing certain files and data. However, if the cache becomes too large or corrupted, it can actually slow down the website. Clearing the cache can help improve website performance.
  4. Plugin or theme conflicts: In some cases, conflicts between plugins or themes can occur due to cached data. Clearing the cache can remove the cached files that may be causing the conflicts.
  5. Broken links or images: If you have recently modified links or updated images on your website and they are showing as broken or not displaying correctly, clearing the cache can help resolve these issues.
  6. Login issues: Cached data can sometimes prevent users from logging into their WordPress dashboard. Clearing the cache can help resolve login issues and allow users to access their dashboard.


Overall, clearing the cache in WordPress can help ensure that the website displays the most up-to-date content, resolves performance issues, and fixes various conflicts or inconsistencies.


What are the alternative methods to clear the cache in WordPress without a plugin?

There are a few alternative methods to clear the cache in WordPress without using a plugin:

  1. DNS Flushing: If your website's cache is being managed by a third-party service or a Content Delivery Network (CDN), you can try flushing the DNS cache to clear any outdated or cached content. Open the command prompt or terminal and type the command: ipconfig /flushdns (for Windows) or sudo dscacheutil -flushcache (for Mac).
  2. Clear Browser Cache: Sometimes the cache issue may be related to the browser's cache. You can try clearing your browser cache by pressing CTRL + F5 (on Windows) or CMD + SHIFT + R (on Mac) when viewing your WordPress site. This will force the browser to fetch the latest version of your website without using its cache.
  3. Clear Cache via Hosting Control Panel: If your website is hosted on a server with a control panel like cPanel or Plesk, you may have options to manage the cache from there. Look for a cache section or similar options in your hosting control panel and clear the cache from there.
  4. Manually Delete Cached Files: If you have access to your WordPress files, you can manually delete the cached files. Access your website files using FTP or the file manager in your hosting control panel, locate the cache folder (commonly wp-content/cache/), and delete its contents. Be cautious while doing this as it could cause temporary display issues until the cache is regenerated.


Remember, if you make any changes to your WordPress site, such as updating plugins, themes, or content, it's a good practice to clear the cache to ensure that the changes reflect correctly on the front end.

Does clearing the cache affect the SEO of your website?

Clearing the cache of a website's visitors does not directly impact the SEO (Search Engine Optimization) of the website itself.


SEO refers to optimizing a website to improve its visibility and search engine rankings. Clearing the cache of a visitor's browser only affects their local copy of the website files stored temporarily on their device. It does not alter the website's actual files or content, and search engines do not have access to an individual user's cache data.


However, there might be some indirect effects on SEO if frequent cache clearing leads to reduced user experience. For instance, if clearing the cache causes slow loading times or missing resources on a website, it may result in increased bounce rates and lower engagement metrics which can indirectly impact search engine rankings.


Therefore, while clearing the cache itself does not directly impact a website's SEO, the resulting effects on user experience and engagement could potentially have an indirect impact.


Does clearing the cache affect the speed of your website's backend?

Clearing the cache on a website typically does not directly affect the speed of the website's backend. The cache primarily affects the frontend user experience by storing and delivering static files, such as images, CSS, and JavaScript, to users more quickly. Backend speed is determined by other factors like server performance, database optimization, code efficiency, and network latency.


However, clearing the cache can indirectly improve backend speed in some cases. For example, if the cache is cleared and subsequently rebuilt, it can help refresh certain data that might have been causing slow response times in the backend. Additionally, clearing the cache can be beneficial during debugging or development stages, as it ensures the latest changes are visible and evaluated properly.
