Technology has made everyone impatient, especially when it comes to using websites. 47 percent of users won’t wait more than two seconds for a site to load when visiting a website, only to be met with sluggish load times and frustrating delays. That’s where caching comes in.
Caching is the act of storing static files on your site in a temporary location.
These powerful cache plugins can drastically improve:
- Performance of your WordPress site
- Enhancing the user experience
- Improving your search engine ranking and ultimately improving your bottom line
But what exactly is caching and how does it relate to WordPress cache plugins?
Let’s put it this way: so every webpage visited on your site requires a request to the server to be processed (including database queries) and a final output that is sent back to the user’s browser.
This output is your website, including all the files and components that make up your WordPress website so that visitors won’t have to reload your site from scratch again.

How to Clear Cache in WordPress Without a Plugin
Clearing the cache temporarily removes stored data such as images, passwords, and browsing history and is crucial for internet security. To remove the WordPress cache manually without relying on a plugin, users can follow these steps. It’s important to note that cached content will need to be regenerated as clearing may temporarily impact website performance.
Every browser and mobile operating system has its method for clearing the cache, but it ultimately leads to a wipe of data. Clearing your cache enables your system to understand the current state of the website or application, helping to prevent potential privacy and security issues.
Clear Browser Cache
Most browsers have a built-in option to clear the cache.
If you’re using Google Chrome there are two easy ways to do this.
- Settings (3 dots) > More Tools > Clear Browsing Data
- Settings (3 dots) > Settings > Advanced > Clear Browsing Data > Select the cached data to clear > Clear data.
If you are using another browser, the above steps are similar, but a Google search “how to clear the cache on {insert-browser-name}” should give you a quick answer.
In Google Chrome you can also press Ctrl + Shift + Delete (Windows/Linux) or Command + Shift + Delete (Mac) to open the Clear browsing data menu. From there, select “Cached images and files” and click “Clear data.”
Clear Server-Side Cache
Clear server-side cache from the hosting control panel or command-line access, following provider documentation or support team instructions.
Clear CDN Cache
If you use a content delivery network (CDN) to cache static content, such as images and CSS files, you may need to clear the CDN cache separately. Log in to your CDN provider’s dashboard and look for options to purge or invalidate the cache. This process may vary depending on your CDN provider.
Manually Delete Cached Files
If you have implemented caching at the application level, such as object caching or opcode caching, you may need to manually delete cached files from your server. You can do this by accessing your website’s file system via FTP or the file manager provided by your hosting control panel and deleting the cached files or directories.
Use Cache-Control Headers
Implement cache-control headers in your WordPress site’s .htaccess file or server configuration to control caching behavior. You can set directives like “no-cache” or “max-age” to specify how long content should be cached by browsers and proxies.
