The WordPress WP Fastest Cache plugin is an easy way to quickly add caching to your WordPress website.

A WordPress cache plugin reduces the resource usage required to run a WordPress site, and speeds it up as well.

Installing the WordPress WP Fastest Cache plugin

Following the steps below, you can quickly and easily setup the WordPress WP Fastest Cache plugin.

  1. Login to your WordPress admin dashboard.
  2. hover over settings click permalinks

    Hover over Settings and click on PermaLinks.

  3. select post name click save changes

    Use something other than Default for how you'd like your URLs to be displayed on your WordPress website.

    The WP Fastest Cache plugin needs to use a Permalink formatted URL in order for it to save a cached copy of your pages.

    I've selected Post name and then clicked on Save Changes.

  4. hover over plugins click add new

    Hover over Plugins and click on Add New.

  5. type in wp fastest cache click search plugins

    Type WP Fastest Cache in the Search box and click Search Plugins.

  6. click on install now

    Beside the WP Fastest Cache entry, click on Install Now.

  7. click ok to confirm plugin install

    Click OK on the pop-up confirmation window.

  8. click activate plugin

    Click Activate Plugin.

Using the WordPress WP Fastest Cache plugin

One of the benefits of the WP Fastest Cache plugin is just how easy it is to use. It only takes a few clicks to have everything up and working. Here are the steps you'd need to follow to get the plugin setup.

  1. click on wp fastest cache

    Click on WP Fastest Cache underneath Settings.

  2. fill in caching settings click submit

    On the Settings tab, place a check beside Cache System, New Post, and Gzip then click on Submit.

    You can try using Minify HTML and Minify Css, but they might break your site. If that happens, click on the Delete Cache or Delete Minified Css and Js tabs and click Delete Now.

  3. set cache timeout click submit

    Finally click on the Cache Timeout tab, then select how ofter you'd like for your WordPress cache to be cleared out.

    Otherwise the cache should clear out any time you publish a new page or post to your site.

Hello Selva Pal,

Thanks for the question. I took a look around the plugin support forum and found this post concerning that setting. It is intentionally set that way. If you have any further questions about it, you may want to post something in the support forum. You can find that forum here. If I find any further information I will add more to this post.

Kindest regards,
Arnel C.

WP Fastest Cache is NOT compatible with plugin iThemes Security which causes a bunch of diff errors. i've allowed the plugin author to login/test on my wordpress site and this is what he told me, "iThemes Security causes the issue. I will try to make my plugin to be compatible with iThemes Security".

What kind of issues did you come across?

I've been struggling with W3 Total Cache for days, but couldn't get my site a lot faster. Then I installed Fasted Cache and the results blew me away! Just fab...

However, I want to add some security to my site as well, and intended to use iThemes. So wondering now what to do...

404 pages not found when they do exist. a url page ALL the content from another unrelated page on the site. the plug in author directly told me it's ithemes security and will try to make his plugin compatible. he came out with a new release but it doesn't mention this fix. i've emailed him to ask him but he didn't answer me when every other email i sent him he answers within a day and he seems very diligent. since he hasn't replied in over 10 days i tried out the new plugin and didn't get any 404s or wrong pages loading on my test site. there's no way in heck i'm enabling fastest cache on my production sites (since all use ithemes). i think he is trying and he seems to update his new version log appropriately so i really don't think the fix is fully in.

.htaccess is not writable, any solutions?

Hello Fran,

It means that the file permissions on your .htaccess file is not correct. The permissions on that file should be 644 if you are using SuPHP.

I'm a bit surprised you recommend only checking Cache System, New Post, and Gzip. I can understand staying away from minify, but some of the other options look OK. BTW, I recently switch my security from iThemes to Wordfence, and I like it better for a number of reasons.

Hi, I am using this for a site which also has a twitter feed in the footer, the feed now doesn't update and always shows the same posts (even when I change it's setting to say, show just one tweet the rendered front end shows the same 2 as before). I suspect the latest posts will suffer the same fate when I ever get around to adding a new post. Is there a known workaround to exclude a footer and it's widgets from the cache?

Thank you kindly.

I would be curious to see it affects the posts and other content as you had mentioned. Is the Twitter feed provided by a different plugin or is it self-coded?

There are many things that can affect speed. Caching is only one of them, though it does have a big impact. You may want to check with a site such as and see what they suggest you correct to make your site faster.

WP Fastest Cash crashed my client's site, and had it down for days before I heard about it.

This error message came up instead of any of the pages on the site:

Parse error: syntax error, unexpected '.', expecting ',' or ';' in /home1/mcfamily/ on line 3

Gonna have to uninstall this plugin.

Thanks for the info. It is always wise to note that plugins are not guaranteed to work with any combination of plugins, and every WordPress installation can be different depending on the mix of theme and plugin support.

It might be best to disable the plugin by renaming its directory from the backend via SSH, FTP, or cPanel File Manager, which file management system you prefer. We have a guide on common WordPress troubleshooting techniques that may be helpful for you.
