See how to configure the settings and purge cache in WP Fastest Cache. It was a winner in my recent Top WordPress Caching Plugins Head-to-Head Tests and is free and easy to use.
Following is a screenshot of all the basics setting.
Below the screenshot are more details for settings that have options or more clarification is needed.
Plus, at the end, you’ll see how to purge the plugin’s cache.
Take note that the first setting is to Enable the plugin.
You wouldn’t believe how many site audits I do where folks install plugins and never configure them, or even turn them on!
I generally turn on all preload options, as they are the most popular posts/pages and will benefit from being pre-cached and ready for delivery.
If you display blog posts on your home page, it’s a good idea to clear the cache for only it.
UPDATE: If you notice the cache not updating properly everywhere when you add a new post, then set this to Clear All Cache. As of Sept 2017, this is the default setting.

When you update an existing post, only select site elements are affected, so I recommend setting the plugin to only clear cache on them, instead of losing speed on the rest of the site.
I don’t recommend setting minification locally for HTML, CSS, and JS. It’s far better done at your CDN, like CloudFlare.
Another big caveat of doing it locally is that it minifies all of your site’s code. Good luck troubleshooting any of that, including your theme, with all the line breaks and white space gone!
This type of compression only works well on Apache host servers. I didn’t see any real benefit in my tests when used on Litespeed servers.
The good news is it won’t hurt anything if it is set on non-Apache servers.
Save Your Settings
Be sure to click the blue Submit button at the bottom.
You should get a green bar notification at the top that your settings have been saved.
Purge or Delete Cache
Click the Delete Cache tab at the top.
And then click the blue Delete Cache button.
If you did turn on minification, then you will also need to delete that cache when you make a css or style change to your theme, or one of your plugins that has a style sheet updates.
I would not recommend using the Other CDN Providers setting if you use CloudFlare. It doesn’t integrate well.
I have not tried the integration settings for MaxCDN or Photon, so can’t say how well they work or not.
WP Fastest Cache does have a premium version available. You have to download and install the free version first, and then you can upgrade from within it. There is a one-time payment per site.

My site audits go deep and reveal the real drags on your site, plus performance holes that are letting bots eat up all of your system resources, making the site slow too.
