Clearing Your Cache In WordPress

by | May 23, 2023 | Business

Caching is a storage of the presentation of data. Caching is vital to contain how much processing power is needed to run your site. It can also be a pain when a cache holds onto old information.

When a user is looking at a database driven web page, there’s a high chance that the view is a cached copy built through processing intensive work on the web server. Caching happens in a number of places:

Web Application Caching

Most web apps and content management systems are database-centric. They hold everything in its database and assemble web pages from that data. That’s flexible, but processing intensive. The more intensive the page build, the longer it takes and the fewer requests can be handled.

We are most experienced at finessing WordPress through caching. We commonly add caching plugins (WP Fastest Cache, Total W3 Cache, WP Rocket, Hummingbird, etc.). When a user complains that they are seeing old content, the WordPress administrator can log into their site, go to the caching plugin settings and “Clear Cache” or similar. This impacts speed and performance in the short term as the cache of pre-built pages is assembled.

Themes like Divi also have some aspect of caching as well. When trying to refresh the view, double check if your theme has any caching functionality that needs to be cleared out.

Web Server Caching

Some Internet service providers offer caching in their hosting. The can be a big win when it comes to the performance.

Clear Siteground Caching

To clear caching in a SiteGround account, you can follow these steps:

  1. Log in to your SiteGround hosting account.
  2. Navigate to the “Websites” tab or a similar section, depending on the SiteGround interface version you are using.
  3. Find the website for which you want to clear the cache and click on its corresponding control panel or management options.
  4. To manually flush the Dynamic Cache, follow these steps:
  1. Navigate to the “Speed” section and click on “Caching.”
  2. In the Caching settings, find the “Dynamic Cache” option.
  3. Within the Dynamic Cache tab, locate the desired website URL.
  4. Click on the “Flush Cache” icon under the Actions column for that URL.

By following these steps, you will be able to manually flush the Dynamic Cache for the specific website URL.

The exact steps and terminology may vary depending on your specific SiteGround interface version and configuration. If you have trouble finding the caching settings or clearing the cache, it’s recommended to consult SiteGround’s official documentation or reach out to their support team for specific guidance tailored to your hosting environment.

Clear A2 Caching

A2 Hosting itself doesn’t do server level caching. Changes have to happen in the applications (ie. WordPress).

CDN / Service Provider Caching

ISPs used to be notorious for holding onto old information: content, nameserver records, etc.. They have largely stopped this practice. Content Delivery Networks (CDNs) still do this as a matter of course.

Most CDNs have a purge option. It will impact your performance in the short term, but it guarantees a fresh view of your content.

Clear Cloudflare’s Cache

To clear the cache at Cloudflare, you can follow these steps:

  1. Log in to your Cloudflare account.
  2. Select the domain or website for which you want to clear the cache from the drop-down menu at the top of the page.
  3. In the top menu, click on the “Caching” tab.
  4. Under the “Configuration” section, you’ll find the “Purge Cache” option.
  5. Click on the “Purge Everything” button to clear the entire cache for your website.

Cloudflare will initiate the cache clearing process, and it may take a few moments to complete. After the process finishes, the cache for your website will be cleared, and subsequent requests will pull fresh content from your origin server.

Purging the cache at Cloudflare removes all cached files for the selected domain, so use this option carefully. Additionally, Cloudflare provides more granular cache clearing options, such as purging specific files or directories, which can be accessed from the same “Caching” section if you need more control over the cache clearing process.

NONE OF THIS WORKS?!?!!

You did all of the above but none of it works? There is one last way to get a fresh view of your content: add junk to your URL.

For example:

https://web321.co/ would give you a cached copy of our web page.

https://web321.co?sfig (the ?slfg tacked on the end) makes the same page come from a fresh URL and a fresh URL is not in the cache, so you get the fresh view of the page.
