Do you want to know how to clear the cache in WordPress? Here is a step-by-step guide for you!
What is WordPress?
You can host and create websites using the content management system (CMS) known as WordPress. WordPress has a template system and a plugin architecture that allow you to personalize any website to meet your online store, blog, or business.
WordPress is a strong publishing platform that makes it simple and quick for non-programmers and programmers to generate and share content.
With plugins and changes to the theme files, users can easily make a static site responsive. WordPress offers a selection of responsive theme options. Being a content management system, WordPress provides many features that make publishing material simple.
What Is Cache?
When referring to websites and browsers, the cache is where pages, files, or other components are saved in memory to retrieve them rapidly.
It could be on your browser, the server that hosts your website, or even a CDN server that is incredibly remote from the rest of the internet. In any case, those files are what your consumers receive rather than having to access a database repeatedly.
This is a brief explanation. However, keep in mind that this is far more intricate than this. But the key remains the same.
Web servers and browsers use HTML instructions to construct pages one at a time. The parts for these pages are kept in several places. These pages will need to be reloaded without a cache.
What Is Wordpress Cache?
Your website keeps the WordPress cache as a server cache to quicken page loading. The benefit of WordPress having its cache is that you can use plugins to control it from your dashboard, change caching options, and erase the cache if necessary.
Caching is a technique used by websites to cut down on data requests and quicken page load times. WordPress must use PHP to send requests to the database on a user’s initial visit.
The HTML page your visitor sees is then created by combining the information. Requesting and reformatting data from the main database takes a long time.
Clean Cache: What Does It Mean?
The files that were only temporarily preserved in your cache data layer are deleted when you clear the cache on your website. Browsers will load the most recent versions of your website pages and utilize those to construct new cache data after you delete your cache.
The permanent data on your website is not removed when you clear your cache files. Only the previously stored screenshots of your website pages are deleted.
Cleaning The Wordpress Cache:
You may ask yourself, “Why would I want to clean my WordPress cache if it makes my page load faster?”.
Cleaning your WordPress cache regularly is part of good web hygiene. You need to reset and clean your WordPress cache in various situations.
Check the last time you deleted your cache if you’ve made updates to your website but aren’t seeing them.
Why Do You Need A Clear Cache In Wordpress?
You may be asking why I want to delete my WordPress cache if doing so speeds up my page load.
Regularly clearing your WordPress cache is a crucial component of good web hygiene. You may need to reset and clean your WordPress cache in any circumstances.
If you’ve made improvements to your website but aren’t seeing them, see when you last cleared your cache.
1. You Updated A Wordpress Plugin Or Theme:
Developers constantly update WordPress themes and plugins. Updates frequently result in quicker and improved performance. Updates are occasionally made available to fix security flaws.
It is advised to delete your WordPress cache whenever you upgrade a theme or plugin. The updates might not take effect if you don’t clean your WordPress cache.
2. You Modified The Look Or Content Of Your Website:
As previously discussed, using a cache allows you to display saved (or cached) copies of your website pages to users.
Returning visitors won’t notice any changes to your design or content if you’ve made any. So, it’s best to delete the WordPress cache after publishing any important updates.
3. You Just Moved Your Website:
Websites can be moved for several reasons by changing domain names or switching to a better web server.
Despite the cause, you should clean the cache if you relocate your website and utilize caching plugins.
If you neglect to clear your cache after changing your server and database, your website may behave strangely and provide a bad user experience.
4. You Set Up A Plugin To Reduce The Size Of Your Images:
Plugins for image compression are great resources for improving the performance of your website and page load time.
Your website will display the outdated previous cache damages if you don’t clear your cache, though.
Hence, deleting the cache after installing an image compression plugin ensures that each image on your website is displayed in its best possible form.

Find out how to clean the WordPress cache and ensure your website functions properly.
Types Of Wordpress Cache:
There are three different forms of caching for a WordPress website:
1. Browser Cache:
A browser is a component of your computer or device that keeps information about a website that isn’t updated frequently. The browser uses its memory to retrieve the data rather than downloading it each time you visit a website. The Network uses less data, and the web page loads more quickly.
2. Cache Plugin:
A plugin specifically created to serve prepared web pages, the cache plugin shortens the time it takes to construct a page from scratch using HTML instructions.
3. Server Cache:
Your host may save previously created web pages in memory for delivery to your visitors, lessening the burden on the server using their cache plugins or scripts.
When one or more types of caching fail to notice when a website updates or don’t think the update is significant enough to force the cache to empty its memory and reload the page, a problem may result.
Because the caching program didn’t keep it for whatever reason, your users might not see new images, updates, or even new pages or articles. The list below demonstrates where the cache is kept on WordPress websites.
It’s possible that you won’t need to clear them all, but we think you should beware of them all to be prepared when the time comes.
1. Clearing Browser Cache:
Starting with the cache of the browser. This is not just the simplest cache to clear (it’s probably tied with most WP plugins) but is also the main cause of you not seeing changes or updates to a website.
This clears the local browser cache, though. If this impacts anyone else, emptying your browser’s cache won’t solve the problem. It’s my solution.
How To Clear It…
1. You should erase your browsing history if the problem only affects you. Each browser has a different method for emptying the cache. However, almost all of them provide this option in their settings or options.
2. You should be able to enter “cache” in the search field after clicking the hamburger or three-dot icon for a drop-down menu, options, or preferences. By doing so, you will be taken immediately to the page where you can clear the cache in your browser.
3. You can use the keyboard shortcuts Shift – CMD – R on a Mac or Shift – CTRL – R on a Windows computer to delete the cache for a specific page within the browser.
- Reloading this way will refresh the files rather than using the cached versions. This does not clear the cache of the browser.
5. Your browser cache may be to blame if you can’t see the modifications you made to your website.
6. Your browser’s cache may display outdated website versions since it keeps data like HTML pages.
7. If you’re using Google Chrome, go to the menu (three dots in the upper right corner of the screen) and choose Moretools, then Clear browsing data.
8. A step-by-step tutorial on deleting browsing data may be found online for all other popular web browsers, such as Firefox and Safari.
2. Clearing Cache Plugin Data:
You should clear the data in your WordPress cache plugin if the issue continues to occur on several browsers or computers.
WordPress caching plugins provide browsers access to cached data. Hence, browsers do not need to download files from the server whenever a user requests a page. Even some well-known security plugins for WordPress that act as firewalls will include caching capabilities.
Installing caching plugins could not be permitted if your website is hosted by WordPress-managed hosting(WPEngine or Flywheel, for example).
If so, they provide the caching through their plugins or on the server, where it may be cleared. There’s a chance they can manually remove the WordPress cache.
If they don’t, on the other hand, you should then call their support staff and allow them to handle the issue. This is fortunate because if what faults that show up are connected to caching, they will be able to repair it and move you forward.
The same rules still apply if it has nothing to do with caching. In either case, you can observe one advantage of managed hosting.
You’ll need a WordPress cache plugin to use caching to speed up your WordPress website.
There are numerous caching plugins for WordPress, most of which feature a “remove cache” or “clear cache” button on the settings page. You can also investigate whether the company that provides your plugins has guides for deleting the cache.

The issue of clearing the browser cache each time you publish a new post is solved if you keep it enabled. Further homepage inspections are the second.
(But, these do not eliminate the requirement that you clear it if you make modifications or updates.)
Moreover, you have the Advanced tab.
This option is good if the browser takes too long to recognize your updates.

Eliminating indemnified files can also be helpful if you’re encountering problems. Like The Cache itself, the plugin regenerates the mass it goes about its business in the future.
Clearing Server Cache:
It’s possible that even without informing you, your host is employing cache plugins on the server. This is especially true if you utilize managed hosting because many use server-side caching, as previously discussed. Client-side caching may consist of:
1. HTML
WordPress keeps the HTML code for your website’s components in many places. When a web browser requests, the server creates the requested page based on the HTML code.
Browsers can reuse these pages thanks to HTML caching. They do not need to start from the beginning each time to develop the page.
2. PHP
PHP pages must be assembled through compilation. To avoid compiling the code repeatedly, the pages are cached.
3. MySQL
The same results are retrieved from the database.
Your host may be employing cache plugins without informing you on the server. This is particularly true if you utilize managed hosting, as many of the muse server-side caching, as we just explained. Instances of server-side caching include:
4. Object
Programmatic objects are cached by WordPress using an object caching API. The typical lifespan of this cache is one request. The items can be utilized again by being cached.
In addition, servers manage sitemaps, virtual file systems, firewalls, and file swapping. Depending on your host, you may be unable to manage server-side caching. You might be able to clear it in your host’s options settings. From Your Hosting plan’s C panel or admin panel, you can verify these options.
The fact that this is not accomplished through WordPress, however, is crucial to understand.
If the setting is not offered, the host might disable it if you ask by contacting support. Frequently, they’ll request that you exhaust all other caching alternatives first. That could also aid in identifying the root cause of your problems.
Some will offer simple workarounds for testing, such as adding /?no-cache=1 to the end of your URL. Every host is distinctive.
Reverse Proxy:
Numerous websites use a reverse proxy type of cache. A Server retrieving resources on a client’s behalf is a reverse proxy. It then sends them back to the client, acting as if they originated from the proxy server, protecting the framework.
The cached version of your website will expire quickly if you’re using an HTTP reverse proxy, like Varnish, and your new content will appear instead.
The options for your provider allow you to change the expiration date for the cache. You can manually clear the cache by using a plugin like VarnishHTTPPurge.
You can modify the cache TTL (Time To Live) settings using a plugin like Varnish Caching and clear the funds.
Content Delivery Network:
The procedure is much the same if you’re utilizing a CDN, with the caveat that you shouldn’t purge the entire cache. The Actual procedure will change based on your host. Well-known is Cloud Flare. Some servers, like SiteGround, even grant you access to the Cloud Flare free version with your account.
Choose the Settings tab from the CDN settings to access your options. The Cache Purge option and a Purge button will then appear. Click it, and your site’s cached files will regenerate and purge to address potential concerns.
Does Clearing The Cache In Wordpress Have Any Drawbacks?
Before analyzing the disadvantages of emptying the cache in WordPress, let’s have a look at the advantages of using a cache:
1. Quicker Load Times
Caches reduce load times by preserving frequently used files and data. These websites and programs don’t need to connect to networks or servers abroad. In Other words, websites and apps can run more quickly after being loaded thanks to local storing of cached data.
2. Get Content Not Through The Internet
The biggest advantage of having a cache is accessing apps and content without an internet connection. This lets us read blogs and articles offline and work on web-based documents.
3. It Saves Power For The Gadget.
Cache promotes energy efficiency and, over time, enhances performance. The device doesn’t need additional energy to visit distant servers because frequently requested files and data are already stored in the cache.
4. Reduced Network Costs
Moreover, caches dramatically reduce network costs. To Put it another way, it reduces network traffic, which lowers costs.
WordPress users frequently avoid clearing the cache because doing so also removes any cached usernames and passwords. Alternatively, say We must re-enter our login and password when WordPress has cleared its cache.
The website may also briefly load slowly after emptying the cache. Once the cache has been refreshed, this issue will be fixed.
Final Reflections:
Cleaning the cache on your WordPress website is a typical solution for issues like login difficulties, slow or unresponsive browser performance, and updates that don’t appear. Regardless of your caching strategies, you shouldn’t encounter any issues implementing this.
Always remember that your host’s support staff is available if you are unsure about doing this. Whatever option you select, your website will immediately load and show every update you make.
we hope that this article has guided you enough on the topic of how to clear WordPress cache.
