Clearing your cache in WordPress can be something you may need to do from time to time when using a caching plugin to speed up WordPress. If you make changes to your WordPress site and don't see the changes when visiting the updated page, you may need to clear your cache. This is because the caching plugin could still be showing the cached version of your page.

To force your WordPress site to show your most recent changes right away, you can delete the cache. Below are steps to clear the WordPress cache in both W3 Total Cache or WP Super Cache.

Clear WordPress cache with W3 Total Cache

If you are using the W3 Total Cache plugin for WordPress, this is how you clear the cache:

  1. Log into the WordPress Dashboard
  2. Performance dashboard W3 Total CacheHover over Performance, then click Dashboard
  3. Empty all cache W3 Total CacheClick empty all caches

Clear WordPress cache with WP Super Cache

If you are using the WP Super Cache plugin, this is how you clear the cache:

  1. Log into the Wordpress Dashboard
  2. Setting WP Super CacheHover over Settings, then click WP Super Cache
  3. Delete cache WP Super CacheOn the WP Super Cache Settings page, click Delete Cache

Once you are done clearing your WordPress cache, you should see any recent changes that you published. The caching plugin should then cache the latest version of your page when the site is visited again.

If you're not using a caching plugin on your WordPress site, then you would not have any sort of caching enabled. I have noticed that Facebook will indeed grab an incorrect image for the thumbnail quite frequently which unfortunately is unavoidable.

Hi,

Can I automatically empty the cache when public a new article or adjourned/modify an article??

Hello Deamon,

I looked at caching plugins above and both of them do allow you to "clear" the cache when you publish a new or modified article. WP Super Cache has the option in the Advanced section. W3 Total Cache has a Preload Cache option and Purge options that basically do the same thing (you would want to purge the cache first, then do a pre-load based on the modification event.

I'm not sure one does it better, though W3 Total Cache allows you to specifically define it as opposed to WP Super Cache where it is simply a checkbox in the Advanced section.

I hope that helps to provide the information you require!

Let us know if you have any further questions or comments!

Hello Deamon,

Yes, in order to use the cache on publish events, you would check that off. And also include conditions for the purging cache.

Hi I have 8 WordPress websites, that are not caching on Google, because of robots files and the robots files are good to go.. Can you help me for the same?

Hello,

Thanks for your question. As long as your robots.txt file is not blocking google, they should crawl your site automatically.

If Google is not indexing your site, you can request that they reconsider crawling it in Webmaster tools; here is a walk through guide.

If you have any further questions, feel free to post them below.
Thank you,

My WP doesn't even have a performance option and the first option doesn't show up either. Why is this and how do I clear my cache otherwise?

Hello Alyssa,

Thanks for your question! If you're not seeing the performance section in your menu, then you most likely do not have the caching plugin loaded. You can find out how to use WP Super cache here and W3 Total cache here. Once you have it loaded, then you can use the article above to clear the cache.

The update should happen immediately. Keep in mind you may have to clear your browser cache in order to refresh the updated information.

Hey, I use Internet Explorer and Google Chrome in private mode. No historical or cookie is saved in the browser. Could be a problem other than the browser?

Hello Fabio,

Sorry to hear that you're having a problem. This doesn't sound like a browser issue. Have you tried it without the private mode to see if the problem is occurring as well? We would need to see a URL, and a before and after situation where you made a change and then tell us what we should be seeing. Give us a little more information and we can try to help you out with the issue, please.

Hey, thanks for helping. The problem that I have is in the Super Cache plugin. I use IE and Chrome 10 browsers in private mode. If I make a change, for example, a comma in a title in the sidebar, there not appears. Only appears when I disable this plugin. :/

Hello Fabio,

Are you saying that you have this same problem, even after clearing the cache as per the instructions above? Once the cache is cleared and rebuilt, then you should be able to see the changes after you clear your browser cache. Browser caching would still occur in private mode. It's just not saved when the session is closed. Try clearing the browser cache in private mode and then see if the problem recurs.

Hello Milind,

You will need to clear the cache files by following the supercache plugin as you need access to the dasboard on the shared server. You may want to disable the plugin (from the plugin menu option on the left hand sidebar) and see if that helps. You can disable the plugin from your cPanel by entering the file manager and then navigating to the wp-content folder. You can then enter the plugins folder and simply rename the folder for the supercache.

I just installed WP Super Cache. When I clicked it shows a message:

A custom url or permalink structure is required for this plugin to work correctly. 

Please go to the Permalinks Options Page to configure your permalinks.

I have choose the permalink that I like, but this message came again.

Please advise. Thanks

Hello Hyip,

Sorry for the problems with Supercache. Basically, the plugin is looking for a "pretty permalinks" setup. It's not clear what you have set for the permalinks, but either it was not saved, or you something set that the plugin doesn't like. The issue is discussed by the plugin author here. If you want to know more about "pretty permalinks" check out this link.

If you hav eany further questions, please let us know.

Hi Jeff, thanks for the helpful article. Quick question:Can you explain what the individual "Purge from cache" feature is doing (link W3 Total Cache adds under my pages when in my Admin–listed right before the WP's Duplicate page feature)?Thanks

The Purge from cache option removes all tmp files so that changes you make to website will show up in your browser.

Hy Jeff, its good to see that you are talking on some small but effective points on Wordpress. My question is, I published around 3-4 posts daily, can emptying cache several times a day good/bad or it will not make any changes to the site?

Hello Ayush,

Thanks for the question. If you are making 3-4 posts daily and your caching plugin is caching those pages, then yes, you should clear your cache AFTER have you completed your latest entries. Otherwise, it's possible that your visitors may say a cached page without your latest blog entry. I hope this helps to answer your question, please let us know if you require any further assistance.

Arnel C.

Hi!
Using one of these plugin AND a service like for example Cloudflare, could be a good choice to speed up a little more website performance? Thank you! :)

Hello Korgzero,

It could speed things up more, yes. CDNs like CloudFlare store the content across multiple servers and send it to the visitor from the closest one.

Hi Scott, thank you very much! :)
I noticed this annoying issue:
I'm on a VPS server. Using W3TC, when I publish a new post I get a 500 error, so I need to purge manually the cache. Is there a way to purge automatically the cache when a new content is posted? Thank you again... your help is really precious :)

this plugin is much more good for cache WP Fastest Cache i use it on my website instead of W3 total cache

The WP Super Cache plugin was causing my admin toolbar thats at the top of my website when I'm logged in, visiable to all visiters and possibly accessible by them too.  I freaked and logged out immediately not knowing if anyone could just click on 'dashboard' and enter the admin area of my site.  Even after I logged out, the bar was still visable as if I were still logged in and if you clicked on anything it would go to the wp login page.  I disabled and deleted the plug in and all is back to normal.  I had to quit W3 total cache becase my site was showing up as a mobile site on a pc.  So I was hoping WP Super Cache would work for me.  Any ideas?

Hello christy,

Thank you for your question. Since both caching plugins are causing problems, you may want to try a different caching plugin.

Alternately, you can attempt to work through the plugin issues. Since many people use WP Super Cache, and W3 total cache, there is a lot of resources when troubleshooting problems.

Turning on Error Reporting in WordPress may provide more detailed error messages.

Thank you,

Hi,

On several sites I see people writing about the fact that Google is crawling to see if you'r mobile friendly and that caching would make the googlebot see 404 errors because the links they saw a few days before are missing after caching... 

I would like to use a caching plugin like WP fastest cache, but for improvement in Google ranking to make the site faster. So if google can't crawl it anymore, the ranking would go down.. Can anyone clear this up?

Thanks!

Hello Ladybird,

Thank you for contacting us. Caching pages does not make them inaccessible to Google, it should just server the requested pages faster. Many WordPress sites use caching plugins, and are successfully crawled by Google.

I recommend using Google Webmaster Tools to review and troubleshoot any 404 errors.

We would be happy to help you review any specific errors you may receive, if you provide them.

Thank you,
John-Paul
