Cache Enabler – WordPress Cache


WordPress Cache Engine

The Cache Enabler plugin creates static HTML files and stores them on the servers disk. The web server will deliver the static HTML file and avoids the resource intensive backend processes (core, plugins and database). This WordPress cache engine will improve the performance of your website.


  • Efficient and fast disk cache engine
  • Automated and/or manual clearing of the cache
  • Manually clear the cache of specific pages
  • WP CLI cache clearing
  • Display of the actual cache size in your dashboard
  • Minification of HTML and inline JavaScript
  • WordPress multisite support
  • Custom Post Type support
  • Expiry Directive
  • Support of 304 Not Modified if the page has not modified since last cached
  • WebP Support (when combined with Optimus)
  • Supports responsive images via srcset since WP 4.4
  • Works perfectly with Autoptimize

Cache Enabler is the first WP plugin to allow you to serve WebP images without JavaScript and also fully supports srcset since WP 4.4. WebP is a new image format that provides lossless and lossy compression for images on the web. WebP lossless images are 26% smaller in size compared to PNGs.

How does the caching work?

This plugin requires minimal setup time and allows you to easily take advantage of the benefits that come from using WordPress caching.

The WordPress Cache Enabler has the ability to create 2 cached files. One is plain HTML and the other version is gzipped (gzip level 9). These static files are then used to deliver content faster to your users without any database lookups or gzipping as the files are already pre-compressed.

When combined with Optimus, the WordPress Cache Enabler allows you to easily deliver WebP images. The plugin will check your upload directory for any JPG or PNG images that have an equivalent WebP file. If there is, the URI of these image will be cached in a WebP static file by Cache Enabler. It is not required for all images to be converted to WebP when the „Create an additional cached version for WebP image support” option is enabled. This will not break any images that are not in WebP format. The plugin will deliver images that do have a WebP equivalent and will fall back to the JPG or PNG format for images that don’t.

Did see some very minor improvements on page loads, at least on benchmark tests. Eventually had to give up on it though because it kept scrambling wpForo. Graphics blown up to 10+ pages long, new posts not appearing for some people, etc. Not worth the aggravation for such minor results. Uninstalled.

Being fanatical about performance, I've tried all of them over the years: WP Total Cache (too cumbersome), WP Super Cache (simple, but also cumbersome with a silly UI now), WP Fastest Cache, Comet Cache, and WP Rocket. Of those, I had settled for Comet Cache, which has the easiest settings. WP Rocket has some Github scripts that allow us to fully serve static files, but the UI of that is needlessly complex as they try to plug "Pro" features. Cache Enabler is absolutely fabulous. We are on Nginx, and it serves super fast static-speed pages. The minification feature works better than anything I've tried (Autoptomize, Clearfy, etc) because it leaves no space whatsoever and does it judiciously; those others "compression/minify" plugins will still leave hard-newlines, which is annoying. All of them. Cache Enabler just works. The UI is minimal, but the magic is maximal. Clearly coded by people who know what they're doing. I've replaced all my plugins on around 25 websites with CE now. Love it. Forget all the "Best Caching Plugins" blog posts all over the web, and get this one. You'll be grateful.

I've played with various caching plugins extensively over the past 5 or 6 years and this one, let me tell you, is the BEST I've come across. Not only is it easy to install with practically zero configuration, it make VERY serious difference to your website without messing up WooCommerce or other plugins that normally conflict with caches. I have this on several sites that are Digital Ocean hosted and accessed via Cloudflare and this plugin is the missing piece of my "go to" setup from now on. Well done developers.. and thank you!
