This plugin requires explicitly minimal setup time and no configuration at all. No coding, no configuration – install and activate, that’s all! Your website is now optimized and loading faster! The WPCacheOn plugin has the ability to create two cached files. First is in plain HTML and the second file is gzipped (gzip level 9). Those static files are used to deliver content faster to your website visitors without any database lookups or gzipping because the files are already precompressed.

WPCacheOn speed-up page loading and improve website score in services like Pingdom and GTmetrix. WPCacheOn will remove any query strings from static resources like CSS & JavaScript files, enable GZIP compression (compress text, html, javascript, css, xml and others), add Vary: Accept-Encoding header and set expires caching ( leverage browser caching). With our PreCache™ technology your website will be cached after the plugin is installed. This means that once WPCacheOn is installed your website already become faster with lower loading time and better results at GTMetrix and Pingdom. ### Are there specific requirements for WPCacheOn to work? The GZIP compression should be enabled in your web-server, no matter if it is Apache, LiteSpeed, NginX or another. If GZIP is not enabled you can ask your web hosting provider to enable it. The .htaccess file in your WordPress instance root folder must have write permissions such as 644. ### Using Redis and Memcached for Improved WordPress Performance with WPCacheOn Redis and Memcached are popular caching solutions used in WordPress to speed up site performance by storing frequently accessed data in memory. Redis: An advanced caching tool for WordPress that stores data in memory to reduce database load and speed up sites. It supports complex data structures, making it highly versatile. Memcached: A simpler caching system used to store database queries or objects in memory, boosting performance by quickly delivering frequently accessed data. Now, with WPCacheOn, you can use any of the caching engines. The configuration is easy: just set the hostname and port. Simple as that and your website loads even faster! ### Enhancing WordPress Management with WP-CLI and WPCacheOn WP-CLI (WordPress Command Line Interface) is a command-line tool for managing WordPress installations. It allows you to perform administrative tasks quickly and efficiently without using the WordPress dashboard. With WP-CLI, you can update plugins, run database migrations, import and export content, and much more—all through simple command-line instructions. We extend the functionalities of WP-CLI by adding two options specific to WPCacheOn. You can purge the WPCacheOn cache and trigger the PreCache. You can purge the cache easily: wp wco cache_flush Just as easily you can trigger [PreCache](https://wpcacheon.io/cache-and-precache-in-wordpress/): wp wco precache ### What to do if I get 500 Internal Server Error after plugin activation? If you get “500 – Internal Server Error” after the plugin is activated, follow the steps below to easily return your website to working state: (1) Login to your hosting account via FTP or File Manager. If you are not sure how to perform that, you can ask your hosting provider. (2) Go to the WordPress installation folder also known as the root directory of your website. (3) Rename the .htaccess file to .htaccess.deactivated. Then rename the .htaccess.wco file to .htaccess. WPCacheOn is using many .htaccess rules related to different web server modules for optimizing the website performance. If some of the web server modules are not installed this will result in Internal Server Error. This is the most common and easy fix to this issue. If this don’t resolve the issue, you can contact us or your web hosting provider for more in depth investigation. ## Reviews ![](https://secure.gravatar.com/avatar/dd8cef4c70bb3a14f5922eb54c92a8166947a303f44eb4a89a954cee4defad6f? s=60&d=retro&r=g) ### 󠀁[Great and simple](https://wordpress.org/support/topic/great-and-simple-185/)󠁿 [tinaponting](https://profiles.wordpress.org/ponting/) Mee 21, 2025 A great and simple plugin, use it several blogs, keep on the good work:) ![](https://secure.gravatar.com/avatar/b57e0cd46c9f1b8c004d3b42681fba81d71ba6d3ee21d93374779833d46d3000? s=60&d=retro&r=g) ### 󠀁[Great speed boast](https://wordpress.org/support/topic/great-speed-boast/)󠁿 [sasaevansc](https://profiles.wordpress.org/sasaevansc/) Julai 12, 2020 Good plugin ![](https://secure.gravatar.com/avatar/5879704e2458d68514a94b996071c613cfc70a9414b27ca0f7943db61dfda58d? s=60&d=retro&r=g) ### 󠀁[Awesome plugin](https://wordpress.org/support/topic/awesome-plugin-5137/)󠁿 [Parichay Chakrabarti](https://profiles.wordpress.org/parichaychakrabarti/) Jun 16, 2020 This plugin helps me a lot to run my website smoothly.

I compared GMetrix results with Swift Performance Light and CacheOn did not have a good score for YSlow test (less than 80%). So I’m not impressed. But it works without problem on the test site and options (very little) are very convenient to check. Better than no cache plugin but I think other well known plugins will do a better job with proper configuration.
