How To Clear The WordPress Cache


When you run a website, you want it to run fast. Sluggish websites are always a no-go. One way this can be done is through caching. Caching works by storing the contents of a website and storing them some place so that they can be retrieved and used. This serves as an alternative to requesting the contents of a website whenever it is accessed through a web browser. As a result, the loading times are much faster. However as a result, when the site is updated, it may not reflect on your web browser. To fix this, we have to clear the cache on your web browser, plugin, host provider, or firewall.

Knowing that, let’s proceed to look at each of these ways.

1. Clearing the Web Browser Cache

Browsers cache websites, this helps the site to be rendered more quickly since the contents of the website does not have to be requested and retrieved repeatedly an is instead stored in memory for a specific period of time. As a result, when users try to access the site, they may not see any recent updates. This often happens but thankfully it’s easy to address since most web browser’s have a clear cache option.

Though differing in how it is done, the cache can is normally cleared through the configuration page. Let’s see how to do this in Firefox and Chrome, two of the most popular web browsers


Here’s how to do it in Firefox. First we select the “Open Menu” button then choose “Options”.

From there we search for the “Cache” in the settings search bar. Once the search is done, we click on the “Clear Data” button, then click “Clear” when the “Clear Data” modal pops up. We then confirm it.

Once that is done, the web browser’s cache should be cleared.

Be sure to check the documentation and consult support of the hosting providers for your hosting provider.
